Audio issues

i have used divxtodvd for moths now and only recently i have been having problems with synch issues with audio any ideas people this is for my own personal use of course

Maybe the input AVI had MP3 VBR (instead of MP3 CBR) as audio? It it is so, you must decompress that AVI’s audio (VirtualDub; Audio__Full processing mode; File__Save WAV) and use that WAV as ‘audio input’ instead of the AVI (or use directly the WAV in authoring).

Most likely that is the case…
