After TMPEGing, how to burn DVD with AC3?

I ripped a DVD and resized it to CVD specs with TMPEG. In the process, DVD2AVI left me a WAV file for the audio portion, which works, but loses the surround sound. Is there a way I can "rip" the AC3 (or DTS) audio from the VOBs and (using DVDit) use that for the audio portion when I burn the new MPG file back to a fresh DVD?

Demux instead of Decode 

Open DVD2AVI and go into the audio setup and select demux or demux all tracks. That will demux the .ac3 file instead of converting it to .wav.

Further testing has DVDit yield the following error: "DVDit recognizes only stereo Dolby Digital, this file has too many tracks." I am paraphrasing, but that is the general error. Any other ideas, please?

OK, thanks for the tips. I tried following the Doom9 guide to Maestro, but then get into menus and buttons and so forth, which I don't need. I just want the movie to auto start. So, can anyone point me to a simpler Maestro tutorial where I can merely add the m2v and ac3 files and have the sucker play?

Some films also have the 2 channel ac3 file. But be careful, most of the time it's the directors comments. If there are two 2-channel ac3's, then at least on will work for you. I believe you can also import the audio into BeSweet and change the 5.1 ac3 to stereo ac3 without any quality loss. You can also change it to a wav or mp3. I'm unsure about how to author CVD's though. I'm not familiar with them. Is this similar to a dvd?

Yes, CVDs are "DVD-compliant" MPEG2 videos, merely half as wide as standard DVD (352x480). But with a high enough bitrate, they look DVD-quality anyway. The upshot is the files are now smaller in size. So, those of us with DVD burners can make longer DVDs (since we can only burn to 1 layer, and not dual layer). At any rate, since I want to preserve the 5.1 surround sound, I have the AC3 file ripped and the CVD-formatted M2V file. Now I just need to find a way to assemble a DVD with these files somehow.

Well, I'm not sure if this will work, but here goes. If you open up ifoedit v. 0.95, click DVD Author from the drop down menu. In here place your m2v file first, then your ac3 file, then your subtitle file and last your chapter file. Press save and select a new folder to store everything, not the source folder though. This will give you vob's. I'm not sure if this is what cvd's require though. Is this the right file extension you need (vob's)? I'm curious, with a 352x480, does that squish your video horizontally? And do you put your files onto a dvd disc? You've got my gears turning.
