Help converting mov sound 2 wav w/ TMPGenc

[sirelf]

Okay , I need some help, I downloaded several superbowl commericals that I want to keep, the problem is that they are in mov/quicktime format. I tried to follow the instructions in the how to convert mov 2 avi thats on this site, but for some reason I can't get TMGenc to demult the sound from the quicktime file, it keeps coming up with a message that the file is a invalid mpeg format,I have downloaded the two plug ins, and put a copy of both in the TMGenc file directory.

So can anyone suggest a alternate program that can rip the wav file from the mov file?

Thanks
