I have a media player in WPF that was previously using the MediaElement control to show video. But on XP it did not show some HD videos. Following this thread's advice I started using the WPFMediaKit library's MediaUriElement instead. Now I can get the HD videos to play, but they have pink lines/distortion going across the top:
That's the top 1/5 of the screen. The distortion will flash at the top for a second, then go away. This happens every couple of seconds. The rest of the video plays fine.
The video plays fine if I open it in Windows Media Player.
Does anybody know what could be causing this?
