XVID To DVD Conversion

[betamac]

I have Perfected my DIVX to DVD conversion but when i try to do the same method for XVID i run into problems when extracting audio with Virtual DUB

when i try to extract audio from an XVID using Virtual DUB i get the following

The requeted audio compression is not compatible with the input format

why is this i am trying to extract the audio with no changes (48000) so i can import in TMPEnc~

Thanks in advance

It is probably AC3. You can use gspot to identify the audio source.

and if it is AC3

or it might work to open the xvid with ac3 directly in TMPGEnc if you have an ac3 codec.
