"It's not Windows XP fault, you are probably just missing some codecs, however WM 8.0 doesn't show you error then it can't find video codec, instead it plays visualisation (nice idea ).
Try to view avi file properties or just install several most popular (divx 3, 4.11, krystal etc.)."
Actually thats exactly whats wrong it says it can't find codecs. Weird. Thanx for the replys.
