Sound goes 20 minutes into film help!!!!!!!!!

Hello everybody hope somebody knows the answer.

I have an Xvid avi film which I extracted the video to Mpeg using Tmpgenc, then I used Virtualdubmod to extract the Wav file, then I used Besweet.Gui to change the Wav file to AC3 then put it all together with Ifoedit to make my DVD.

Well I have an excellent picture and the sound is in Sync but 20 minutes into the film the sound goes and never returns but the sound is correct on the avi file!!!

So somewhere when I have extracted the wav and changed it to AC3 the sound has become corrupt what shall I do excellent film and dying to watch the rest with Sound.

Right I think I have put this in the wrong thread not sure but I have now reencoded the whole film again and extracted the audio wav file using Virtualdubmod and then converted using AC3 machine and used Besplit after to fix the Ac3 file and put it together using Tmpgenc DVD author and this will only put the file together to the same bit where the sound goes the Wav file from Virtualdubmod will play fine there must be something when I am converting it to AC3

Please Please somebody help me I have run out of ideas now havent been doing this long and all my other finished DVDs have been spot on.

IM STUCK

 

Still here trying to solve this somebody must have an answer out there

 

I'm doing a thread all by myself here right the problem is the wav file is fine but when converting it to AC3 its only converting 20 mins of sound god knows what happens to the rest of the sound.

Does that help somebody to help me? does nobody want to help me? Am i on my own here!
