Yeah, VirtualDubMod works great now for demuxing. For a while I wasn't using it since it wasn't able to extract the subtitle streams as well and I used the command based ogmdumuxer. Now VDMod is great, though, I still wont use it to merge OGMs and still use OGGMux, but I like to use it to chapter files that weren't chaptered. I also use winamp to decode the ogg to wav. That way I don't have any problems with TMPGEnc...
