Sound messed up with 23.97 Fps

After compiling several AVI files in 23.97 format with Mpeg sound 96Kbps the whole
sound is messed up. Skips/repeats and 3-5 seconds ahead in time..
I did select the 25 Fps profile since there is no 23.97 format.
What am I missing here??

A lot...a whole different sampling rate? That's a BIG deal. Not a little one. going from 24 to 25 makes a big difference as well.
Why on earth did you mix all this up? Just render the avi at the frame rate, and drop into DVDA as an avi, or render an m2v stream with an AC3 file from Vegas, either way you'll be right on. But messing with even one sample or one frame is merely asking for trouble. Especially with MPEG.
How did you edit the movie? How did you render it? If you rendered a video at 23.97, and the audio at 25., then that's a HUGE difference. Same if you rendered the vid at 23.97 and the audio as a 29.97 mpeg2 or 3 audio file.
Waht was the original sampling rate of the audio? 48k? 44.1? 32?

Somehow, all the things I recorded ended up as 23.97 Fps with 44.1 Khz sound (1 avi file)
I dropped it into DVDA and the preview looked just fine.
then I wanted to convert to DVD the Msgbox came up, that it had
to Recompress the video track and the sound track.

So, best thing is to demux and then process seperately?

Yep...if that's what you are getting.
Was the original media 24 p?
