Interestingly the card is only working on real Intel 32bit hardware and in combination with WinXP SP2. Intel32+Vista, AMD64+Vista64, AMD64+Vista32, AMD64+WinXP are not working with the same card. Surprisingly a real old S3 SavageDDR chip was at least able to play audio files - but no video (damn, no testing on my notebook).
Anyway, my ultimate goal was to get the stuff working in a Avalon Express Application. I can create, compile and run the Avalon Express C# template. Also adding a button to Pag1e.xaml works. But as soon as i add a MediaElement (even without source attribute) the PresentationHost crashes on startup.
Any idea? Creating those stuff as an Express Application would be really cool to create a web based Avalon Test Server (people could modifiy XAML files and when they open the test url, the server compiles the project and delivers the exe inside the browser).
Oh, and is there a way to interact with the presentation host via JScript? e.g. recieving events or user input from a "normal" html based website?
