the audio on the movie gradually goes out of sync, but then after about 17 minutes into the video, it goes back into sync. It is just an episode, and lasts about 20 minutes.

I've tried using virtualdub to export the wave file and using that as the audio source in tmpgenc, doing both direct stream and conversion to 48000 in 16bit stereo also tried saving the wave and avi into a new avi and using that as both audio/videio in tmpgenc,

i've looked at any forum with the word 'sync' in it and none of the suggestions in any of them have helped me - same with any tutorials.

Tmpgenc gives me an error about not being able to use tooLame.exe as an external decoder when i've tried using it.

anyone have any ideas?
