I have put MC17 on both my laptop (Windows 7) and my desktop (Windows XP). On Windows 7, it plays every wmv I throw at it. On XP, it play some wmv files, but the ones with bitrate of 2079kbps and dimensions of 640 x 480 you just get a blank screen and no playback. I believe it is all to do with the bitrate.
I've tried changing some settings on XP, but with no success
Any ideas anyone?
