im getting this problem on virtualdub with a divx avi file.
what do i do?

"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 16271 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 encoder" (bitrate 132.8 11.8) kbs

what program recompress's with a constant bitrate encoder?
any ideas?
anyone in similar situation? what did you do
