Hi guys, Quick general ffmpeg question I'm hoping somebody here can solve. I've used ffmpeg to convert video files to .wmv format. I've tried every codec (wmv1, wmv2, etc.). The files play perfectly on my Vista machines, but will not play on ANY XP machine, using the latest WMP. I've tried all sorts of codec packs on the XP machines to no avail. Is there any specific codec that can be downloaded that is guaranteed to play the ffmpeg converted wmv files on XP? Thanks!
