I am having a rather odd problem while encoding divX movies with Virtual Dub (I use the tutorial on this site, but I still have this problem using other methods) When I encode the movie it works just fine on my PC, but when I try to play the movie on someone else’s computer (using the same version of DivX 5.0.3) the movie is sluggish and when you skip to a latter point in the movie it takes about 30 seconds for the audio and video to go back in synch. When I spilt an AVI file it again works fine on my computer, but on other computers the audio is very badly out of synch (I would say up to 2 seconds) and stays that way. I burned the movies to CD at 4X and transfer them across my home LAN with the same results every time, so I don’t think that I am experiencing any file corruption problems here. Could this have anything to do with CPU optimizations? I encode them on an AMD based system, but all of the other computers are Intel bases (Celeron or PIII)? Any help would be appreciated.
