Strange audio glitch when converting from avi to mpeg for DVD.

[silmarallion]

I have been asked to create a DVD.
The source file is avi (recorded on an Archos system I believe). It plays perfectly with VLC, WMP, etc.
Now what I need to do is convert the avi to an mpeg using TMPGEnc so that I can burn it using DVD Lab Pro.
I am converting to MPEG2 (audio & video)
The problem I am facing is that the finnished mpeg file looses audio about 3 seconds in (8min file).

What I have tried so far.
TMPGEnc
Convert to MPEG2 system (audio+video)
Convert to MPEG2 ES (audio+video)

AVI2MPG
Won't read the avi
It get's stuck at "Searching for actual last video frame" "Checking DirectDraw sample update completion status, time = xx sec"

Cut Assistant
Cutting the source avi file into parts (cutting off the start/end as well) with hope that I would skip the glitch and the sound would then work after I have converted to MPEG. This didnt work.

DivFix & DivFix++
I have tried checking for errors and fixing the avil file before using TMPGEnc to encode the fixed files to MPEG.
The orignal file is reported as having the following error;
"Error detected at byte: 192324576
Skipped 552 bytes.
Index frames detected.
Error detected at byte: 192325136
Skipped 8 bytes.

New Stream Size : 192322532
Total Error Count : 2
Total Frame Count : 22764
Video Data Frames : 11382
Audio Data Frames : 11382"

The fixed avi reports no errors but the audio still stops after a couple of seconds when it has been converted to mpeg.

Ulead
I then decided to use Ulead to create an image of of the DVD so that I could extract the mpeg file that Ulead converted from the image. But I found that the audio cut out at the same point.

I'm now all out of ideas and am desperately in need of help. Any suggestions?

Peace.

Have you tried demux the audio? Use avidemux, open avi and under Audio->Save. Or convert it directly to wav, under Audio->Encoder choose PCM as audio codec and Audio->Save.

Then try play the audio file, if it sounds okey you can load the video and then the separate wav under audio in tmpgenc.

Thanks for the advice Baldrick.

I tried Audio-->Save. It saves the audio as a file without an extension. So I tried adding the extension .wav and as I expected that didn't work (should it have?).

I also tried to find Audio-->Encoder, but there was no encoder option under Audio. I'm running v2.5.1.
Was the Encoder option for a seperate app?

Edit - I think I have worked around the problem. I used AVIDemux to convert the AVI to an MPEG (A+V). I then loaded the MPEG into AVIDemux and indexed it. This allowed me to save the audio as .MP2 in TMPGEnc which I then transcoded to .WAV.
I am now saving the video through TMPGenc and will let you know if I succesfully mux them, keeping audio in tact.

Just for the heck of of it, why not go try DVDflick or ConvertxtoDVD, AVStoDVD etc..Can't hurt!...
