DLed Movie,Plays Fine in Beginning..Then Goes Out of Sync?

[vWvSTATICvWv]

Just wanted to thank you guys for helping me with my purple issue with my movies in a post below.

Anyways, if any of you guys have downloaded part 2 of Halloween Resurrection, then you know what im talking about here.
The movie starts out fine. Then a lil past the middle of part 2, it starts going out of sync and it looks as the movie is a lil jerky or buggy?
Then i noticed at the end when the credits are rolling, the song/rap is sped up really fast and the credits are scrolling fast.

I have virtual dub as well as TMPGencoder. If anyone could help me out on what i can do to maybe fix this, i would appreciate it. I prefer to use TMPG but if i have to use virtual dub to fix this, then so be it.
Either way...Thanx in advance.

Try this to fix out of sync:

This to extract audio as WAV and use as audio source in TMPGE:

and this to check for bad frames(which can be extracted):
scroll down to Virtualdub version called mp3_freeze.
