I can't work out wants wrong here I shall explain what I have done
Xvid film changed Video to Mpeg using Tmpgenc
used virtualdubmod to extract wav from xvid
then used BesweetGui to change wav to AC3
then used Tmpg DVD author to put it all together
Well the sound is well out of sync but not on the original xvid
Then I used ffmpeggui still the same
I was told to try Tmpg AC3 plugin but that does not give me the option to change wav to AC3
I now must have authored this film about 15 times each time the sound is out of sync far too much to each think about watching
Can anybody help the problems lies with changing the wav to AC3 but I can't think of an answer
PLEASE HELP

Did you use Full Processing when saving the .wav?
Is the audio the same length as video?
You can try using Goldwave, with the "Timewarp" feature.

Hi
Yes I used full processing with no compression and saved wav
No the sound file isn't the same size as the video should it be then,
I have never had this problem before and I have done quite a few and how do you use that program gold something or other what I can't understand how come the xvid is excellent and I really want to watch this film

Right the Xvid file is 1hr 34,mins but the mpeg file is 60mins but the AC3 sound file is 1hr 34 mins, so what can have gone wrong when converting it I used TMPGEnc and I checked with AVI codec to get the correct settings?????????

If there's any problem with the AVI, TMPGEnc will mess up.
First check the xvid for errors, bad frames, etc.
You will either have to re-encode the AVI, or remove the bad parts.
virtualdub (mod, mpeg, or mp3) will all do it easily.
To use goldwave, you load the .wav audio file, select Effect, TimeWarp, and make the audio whatever you need.
Save as .wav, then transcode if needed.

How do I check the Xvid without sitting and watching at my computer?

Careful, sometimes VirtualDub says 'WAV' just to say 'it's a sound stream', but the sound can be a compressed sound which VirtualDub cannot decompress (e.g. AC3 or DTS). The same happens in VirtualDubMod when you click 'Save WAV': the result might the same of 'Demux', even at least it shows, on the Stream__Stream List page, the correct extension.
Is the sound stream large 10.1 MB x length of the audio steram? I think not.
First of all, are you sure that that the original AVI had AC3 sound? Load it woth VirtualDubMod, do Stream__Stream List and read which type of stream is.
This because that 'un-sync' problem is often related to VBR MP3 audio, not AC3.
In any case, try to apply the 'sticky' threads (which no one reads, alas): http://forums.afterdawn.com/thread_view.cfm/190445 or http://forums.afterdawn.com/thread_view.cfm/129217 .

No in the Xvid the sound was MP3 which I converted to AC3 and I do look for things to read have checked everything I can find on Afterdawn guides and forums and I have given up now on this film I have been doing it for 3 days and download more programs to try and fix it and read soooo much stuff.
I think the video has some errors in it, I have another xvid film to try fingers crossed this one goes to plan otherwise I am just going to scream
Thanks for all your help I have been beaten

If you want to make an extremally hard and complicated thing to avoid throwing away that movie, you could:
- uncompress to WAV the stream (check if that WAV is a real uncompressed WAV. Is it 10.1 MB x length large?)
- re-encode, using that WAV as 'audio input', to MPEG-1 that AVI
- 'examine' when the A/V goes out-of-sync. Since that video MPEG-1 file will be 'dummy', and used only to check A/V sync, set the maximum speed your encoder can use, the video quality is irrelevant now.
- sign in the point when the sound, due to the coruption, goes out-of-sync and 'estimate' how much, in + or -. Use Exact Audio Copy, do Tools__Process WAV and open the WAV; in that point correct the WAV, either deleting some stream (if the sound is 'over' the video) or inserting silence (if the sound is 'before' the video) . If EAC cannot load the 'WAV' you extracted a 'false WAV' from the movie, due to the corruption. You'll have to extract a 'real WAV' from the MPEG-1 movie you just made (the encoder will make a 'real' sound by losing A/V sync).
- encode AGAIN that AVI to MPEG-1, to see if, again, you need to correct the WAV or if the A/V is OK in the whole movie.
Once the WAV is OK, you can make what you want with the AVI (video)+ WAV (sound)...
