Jason over at Digital Media Thoughts sent me an email about his new article on The Powers and Perils of a Platform.  Jason talks about the trouble he had when a Media Center 'plugin' went bad and couldn't be uninstalled.  It's not clear if it was an HTML application or a managed code add-in, but based on the description I'm assuming it's the latter.  He ran into problems when trying to manually uninstall the application so I thought I should post something on what to do when an add-in goes bad...

In Media Center 2005 add-ins can do pretty much what they want to do without restriction, if one starts to misbehave the best thing you can do is to disable it:

1. Start Media Center
2. Click on Settings
3. Click on General
4. Click More Programs Options
5. Click Edit More Programs
6. Deslect the app to disable and click Save

This will disable the app from starting and hide anything entrypoint it's registered throughout Media Center.  It won't uninstall the app, but it will prevent it from running.

The new PodShow+ site, unleashing pretty darn soon, has a personal bio feature called 'The Legend of me'. I just filled mine out. Here's what I wrote:

I'm a programmer with an apetite for timeshifted media. That pretty much sums it up. In 2000, before I'd heard of RSS, I was using Voquette Media Manager to record Real streams of This American Life, which I'd lovingly burn to CD and listen to on long car trips. Later, in the days of 'audio blogging', I used the Radio Userland news aggregator to automatically pull MP3 files from enclosure-bearing RSS from Dave Winer, Chistopher Lydon and Doug Kaye. I'd then locate these on my hard drive and drag them, one at a time, into the media management software for my Neuros MP3 player. It worked, sort of, but was too much effort, and there was still too little content (especially after Chris took a break) for practical daily use. Adam Curry switched me back on in 2004 with a steady stream of daily content, developer feedback, feature ideas and a critical insight that made the medium: we needed automatic sync to the listening device. The early innovations in podcasting were nearly all Mac-only, which as a Windows user drove me nuts. Erik de Jonge's 'iSpider' project had a decent command-line Python/Applescript codebase, and were up for doing a cross-platform GUI product, which is where I wanted to go. Bringing in some modest COM knowledge that Pieter Overbeeke's 'i-podder' javascript helped me learn, I joined the iSpider team and Lemon was born. Nearly two years and one Ceast and Desist later, Lemon is now known as Juice and has accumulated over 2 million downloads. Along the way, Martijn Venrooy and I built the GigaDial 'podstation factory' (October 2004), and in Fall 2005 I joined PodShow and moved my family from Boston to San Francisco. At PodShow I do a mix of engineering (DGAP, Golden Tickets), developer relations (developer.podshow.com, DevCasts), technical reviews of potential partners and, when anyone will listen :-), talent scouting. I'm bullish on New Media and on the lookout for cool new stuff to build, to make listening and viewing better.

Pretty verbose --- it fills the alotted space on my profile page --- yet it barely scratches the surface.

MSN Remote Record is live and out of beta.  In simplest terms it's a way of browsing the same TV guide as your Media Center PC uses and then remotely instructing your Media Center PC to record something.  Pretty clever stuff.  There's a small download for your Media Center PC and then it looks pretty easy to use.

Try it and let me know what you think.

All the keyboard shortcuts for Media Center for those times when you just don't want to use a remote control are documented here.

Update: If the page doesn't display, try again later, it's propagating around servers or something like that I'm told

Betanews reports that Gateway/eMachines will be offering a new Media Center PC for $599!  The specs are pretty impressive for such a cheap computer:

• AMD Athlon 64 3400+
• 1GB DDR SDRAM
• 200GB hard drive
• ATI Radeon Xpress 200
• 8 in 1 media reader
• Rewritable dual-layer DVD drive
• CD-ROM drive

Wow.  No mention of a TV Tuner, monitor or remote though... 

I've never bought an eMachines computer before, but that seems like a great deal for a pretty powerful system.

I've had a couple of questions by email that I should answer (note I've paraphrased some of these):

What fonts should I use for my HTML Media Center application and can I use Flash?  The SDK is where to go for design guidelines for HTML applications (the short answer is to use a sans serif font).  Yes, Flash can be used in HTML Media Center applications - Napster and MSN Music both use Flash.

How can I add an application to the Start Menu?  You can't.  Well OK, you can, but we recommend that only OEMs use this functionality as there is a limit to how many applications can appear on the start menu and adding a new app will stomp on existing applications.  If you intend to distribute your application you shouldn't do this, but if you really want to know, the details are in the SDK here.

I've seen the Media Center software for sale online is it OK to buy it?  I'm no lawyer so I'm not going to comment on this.  Media Center is an OEM product and only available with new PCs is the official answer though.

I'm back home from @media 2006, which as you probably know took place in London last week. I'd like to follow suit with the many other people who have posted their reflections on this year's conference.

Like last year, @media 2006 was a success. I enjoyed myself thoroughly during my four days in London, mostly thanks to the fantastic people I met and spent time with.

...For nearly five years, George W. Bush and other members of his administration have been proclaiming proudly that they have been tracking terrorist financing through international financial institutions.

...The House of Representatives passed a resolution saying it 'expects the cooperation of all news media organizations.'

In a few days I'm leaving for London to attend the @media conference. I hope it will be as much fun as last year was, but it's a bit different for me since this year I am one of the speakers. I'll only be sitting in on a panel (Strategic CSS Project Management), not holding a full presentation of my own. I'm still a bit nervous about the whole thing, and looking at the names of the other speakers gives me a surreal feeling.

If you're going to @media and see me standing in a corner trying to make myself invisible, come and say hi. I promise I won't bite. Well, unless you start talking about alt tags ;-). I am a very approachable kind of person most of the time, but I do tend to be a little shy among people I don't know. In other words, don't wait for me to start any conversations.

A client recently reported that there was a problem with their print stylesheet causing content to be cut off at the right margin. I had a look at it and couldn't see a problem until I tried printing from Internet Explorer. There was a problem alright.

It was really puzzling since all the print CSS for that site does is basically hide parts that are irrelevant when printing. There shouldn't be any conflicts with other style sheets either since the screen style sheets use a different media type. But I was wrong - in some cases IE will apply CSS that it shouldn't.

I've decided to take all the questions I get by email and answer them on Fridays in one post, so do please continue to email me any questions you have.  That said, here's this weeks questions:

How can I keep the Media Center window on top so I can work on other things?  In Media Center go to SettingsGeneralStartup and Window Behavior and select 'Media Center window always on top'.

How can I associate an HTML application with an add-in?  Register both the add-in and the HTML page together.  Instead of registering the HTML app and the add-in you need to register them both as a single application with multiple entrypoints - one entrypoint for the add-in and one for the HTML page.  This will make them both part of the same application and so from a background add-in a call to ApplicationInfo.IsForeground will return 'true' when the HTML page is currently being displayed.

MSN Video Download  apparently went live today with a choice of two membership types  Premium and Basic.  Premium is $19.95 a year and has more content than the free Basic membership.  Not wanting to commit myself to a membership yet I signed up for the Basic membership, thinking I could load some videos on to the miniSD card in my smartphone....

Sign up was easy, I used my passport account, agreed to the terms and installed the download software.  The download status page showed content was downloading from Fox Sports.  In order to sync content to my phone I needed a smart playlist so I followed the instructions to download one.  This was the first problem, the instructions used Windows Media Player 9 and I'm using Windows Media Player 10, a little strange, but not a huge problem.  With the smart playlist in place I thought I'd be good to go...

That wasn't going to be the case though.  I started by trying to play a video in Media Player directly and got prompted for a username and password which was being requested by 'admin.theplatform.com' not 'msnvideodownloads.com'.  I tried my Passport email address and password which might not have been a great idea, but it didn't work anyway.  Meanwhile I could see that Activesync had been trying to sync the content to my phone so I checked the Sync page in WMP.  Nothing had been synced, instead  there was an error message 'Windows Media Player can not synchronize the protected file.  Protected files can not be converted to the required quality level or format'.

Now I have almost half a gigabyte of content (and it's still getting downloaded) and I can't watch any of it.  If anyone gets this working I'd love to know how.

I've had lots of questions recently and no time to really get answers and post them up here.  If I haven't answered you question it's because I don't know the answer and haven't had enough time to get to the bottom of it yet.

First of all I had a couple of questions on MSAS which I don't know that much about.

Can I tell which tuner is being used when a recording takes place using MSAS? No, you can not.  What you can do, which may or may not help is use OnTVRecordStateChange from a background add-in which will give you a GUID and you could track which was in use - this won't help if a tuner is being used for live TV though.  Here's a code snippet on how to use OnTVRecordStateChange:

void IAddInEntryPoint.Launch(AddInHost host)
{

host.Television.OnTVRecordStateChange += new Microsoft.MediaCenter.AddIn.TVRecordStateChangeDelegate(TvRecordStateChangedHandler);

...

}

public void TvRecordStateChangedHandler(object obj, Microsoft.MediaCenter.AddIn.TVRecordStateChangeArgs TVArgs) {

if (TVArgs.Started)

mcHost.HostControl.Dialog('Recording started on tuner ' + TVArgs.Tuner, 'TV Recording',1,10,false);

else if (TVArgs.Stopped)

mcHost.HostControl.Dialog('Recording stopped on tuner ' + TVArgs.Tuner, 'TV Recording',1,10,false);

}

Can I use remote desktop to connect to a Media Center PC? Yes.  You can even use Media Center, but it won't play video over a RDP connection

Can I use animated backgrounds in an HTML page? Not really a media center question, but I don't see why not, use an animated gif.

Could I create an add-in that played a selection of WAV files with a gap between them? Yes, using Playmedia and Playrate you could contstruct an addin to do this - waiting until the playrate was stopped, then wating however long you want before playing the next file.  You could also use More With This  to make this work with any folder of audio files.

Can I use ASP.NET for development?  Yes.  You can use any web technology that outputs HTML.

Can I use WinForms for development?  Yes, but if you're running as a .exe you won't have access to Media Center APIs.  If you're running as a .NET applet in a webpage you'll have access to the Media Center APIs from the HTML page and will have to communicate between the page and the .NET applet to use the Media Center APIs - non-trivial to do, but not hard.

A big day indeed: it’s finally sunny (cause for celebration in and of itself), it’ Friday, it’s the end of the quarter, and we’re about halfway through the year. Our company shipped some major products this week, though for various reasons the press release won’t be out until the second week of July. And I have some other news that will have to wait until Monday, for various reasons.

In the meantime, it’s a good sort of day to sit down and shuffle through the iPod and see what comes up:

1. Bob Dylan, “Hurricane,” (Desire)
2. TartanPodcast, “Sleepy Sunday Show #10”
3. Moby, “Memory Gospel,” (Play: The B Sides)
4. Eva Cassidy, “Songbird,” (Eva By Heart)
5. M. Ward, “Oh Take Me Back,” (Transistor Radio)
6. Neko Case, “Knock Loud” (Fields and Streams compilation)
7. Robert Shaw Festival Singers (Arnold Schoenberg, composer), “Friede auf Erden (Peace on Earth), Op. 13” (Evocation of the Spirit)
8. John Coltrane, “Blue Trane (alternate take),” (Blue Trane)
9. Clem Snide, “Moment In The Sun” (The Ghost of Fashion)
10. The Stills, “Love and Death” (Logic Will Break Your Heart)

In yesterday's announcement of the new Zune media player and Zune Marketplace, Microsoft (and many press reports) glossed over a remarkable misfeature that should demonstrate once and for all how DRM and the DMCA harm legitimate customers.

Microsoft's Zune will not play protected Windows Media Audio and Video purchased or 'rented' from Napster 2.0, Rhapsody, Yahoo! Unlimited, Movielink, Cinemanow, or any other online media service. That's right -- the media that Microsoft promised would Play For Sure doesn't even play on Microsoft's own device. Buried in footnote 4 of its press release, Microsoft clearly states that 'Zune software can import audio files in unprotected WMA, MP3, AAC; photos in JPEG; and videos in WMV, MPEG-4, H.264' -- protected WMA and WMV (not to mention iTunes DRMed AAC) are conspicuously absent.

This is a stark example of DRM under the DMCA giving customers a raw deal. Buying DRMed media means you're locked into the limited array of devices that vendors say you can use. You have to rebuy your preexisting DRMed media collection if you want to use it on the Zune. And you'll have to do that over and over again whenever a new, incompatible device with innovative features blows existing players out of the water. Access to MP3s and non-DRMed formats creates the only bridge between these isolated islands of limited devices.

The real culprit here is the DMCA -- but for that bad law, customers could legally convert DRMed files into whatever format they want, and tech creators would be free to reverse engineer the DRM to create compatible devices. Even though those acts have traditionally been and still are non-infringing, the DMCA makes them illegal and stifles fair use, innovation, and competition.

May this be a lesson to those who mistakenly laud certain DRM as 'open' and offering customers 'freedom of choice' simply because it is widely-licensed. With DRM under the DMCA, nothing truly plays for sure, regardless of whether you're purchasing from Apple, Microsoft, or anyone else.

Take action now to support DMCA reform and to stop the government from mandating more DRM.

[Postscript: In an interview with Engadget, Microsoft Zune architect J Allard pointed out that Zune has sufficient video format support, in part because there's 'Lots of DVD ripping software out there that encodes to those formats, so the most popular formats out there, whether it's MPEG-4 or H.264, we'll support those.' Gee, he isn't suggesting that his business model benefits from customers using tools like DeCSS or Handbrake to evade the DRM on DVDs, right? Especially since Microsoft is furiously trying to squash the FairUse4WM tool, that would seem rather hypocritical.]
