Religiously followed Afterdawn's guide on DVD to XVid+AC3 conversion. After installing the Audiofilters package from doom9 I can hear the resulting AVI but instead of 5+1 the sound only comes from R,L, Rear R, Rear L and sub channel (the central channel is muted). This happens both with BSPlayer and WMP. The AC3 I am multiplexing into the AVI (with VirtualDubMPEG) sound perfectly 5+1 when played by itself with Creative Playcenter. HW is Creative Audigy+ Inspire; OS is XP Pro Please please please please ... can anyone help me ? Thank you very much. Bob PS Is there a forum to make feedback on a specific Afterdawn guide ?
