improper vbr audio encoding?

[Lashford42]

i have two xvid avi's that i want to join together and re-encode into either divx or xvid. when i try to open the xvid files, it says "VirtualDub has detected an improper vbr audio encoding in the source avi file and will rewrite the audio header with standard cbr values during processing for better compatibility. this may introduce up to 3679 ms of skew from the video stream. if this is unacceptable, decompress the 'entire' audio stream to an uncompressed wav file and recompress with a constant bitrate endcoder (bitrate: 157.7 +- 13.9 kbps)" is there no way i can just add the files without decompressing everything separately? am i missing some codec or tool? thanks for the help ya'll.

1) This has got nothing to do with XviD; XviD isn't an audio codec.
2) You've got a VBR soundtrack there, VirtualDub doesn't like that. Get VirtualDubMod or Nandub.

okay... i ran virtualdubmod and everything, but it still says that detected the vbr file and will try to convert it to cbr and there may be skew and all that. i tried to append the next avi segment to the first, but it said it couldnt do it b/c the audio streams have different sampling rates.. what am i supposed to do, and what does vdubmod do different???

resample the audio.
use video info to check how its different and change one of them to the other.

1. recompress the video in virtualdub
2. extract the audio to a wave file in virtualdub
3. rename the file into *.mp3
4. open the video file in nandub and mux the video with the audio
