I have the first part of Spider-Man that I got off of Share Reactor. I extracted the mpeg files with the GUI version of VCDGear. Everything went fine untill around 35:04 when the sound went of sync by 5 to 10 seconds. It got normal at about 38:27. I thought it might be DivX 5 (which I had just installed) so I unistalled it and restarted my computer but that didn't do it. I also mesed around with my resolution but that did nothing except give me a headache. I was using the latest version of WMP (which I've had no problems with) . I tried Real Player but it keep performing illegal operations. What's the problem with the movie and how can I fix it?

Thanks.
