I captured some video with a Matrox G200 card and burned the video to a cd. I now have a ATI AIW 7500 and tried to play the video and it wouldn't work. Avi Info say it's using dmb1 compression and that's a Matrox thing. I checked MS update and I have the latest Media Player and codecs. I can get the sound to play but no picture. Short of reinstalling the Matrox card and saving it in another format, how can I get it to play? Matrox's web site doesn't seem to mention dmb1. I'm stumped.:disgust:
