As the title says when I replace the VBR audio on a DivX with a CBR audio (all mp3) using VDub I get synch problems. I did what VDub suggested - ripped the audio to Wave and then recompressed and muxed with the original video stream.

Any ideas where I'm going wrong?

Audio is VBR, ave rate 136, 48000Hz, MP3.

TIA
