I had a service transfer an old VHS cassette to DVD so I could edit it. (My own VCR is fairly crappy.) I can easily extract video from the DVD, but the audio is unusable. I can copy a .VOB file to hard disk and play it using PowerDVD. I can use vobsplit, and the smaller .VOB also has good audio.
But I have tried to extract .avi or .mpg files, or .ac3 or .wav files, with no success. I tried VirtualDubMod (1.5.1), which acts as though it's processing the audio stream, but the resulting .avi files don't have audio readable by any of my editing tools (ScreenBlast, Windows Media Player, ArcSoft Showbiz). I've extracted a .wav file (using VirtualDubMod) and Windows Media Player fails to play it, complaining that it can't download the codec. I can't extract with Fair Use, xDVD, DVD2AVI, and other tools whose names I've forgotten. I've also tried the trick of renaming the .VOB to .mpg, which gives me some different error messages. (MS Media Player says "Class not registered")
What's frustrating is that the .VOB has working audio, but I just can't seem to get at it. Again, no problems with the video. Any suggestions? (Apologies in advance for such a newbie question, and yes, I have repeatedly searched the forums here and followed all suggestions that seemed even remotely relevant...)

Open the VOB in Vdubmod, go to streams>stream list, right click the desired audio track and select "full processing mode", then click on "save wav".
Close Vdubmod and open the avi with no sound, go to the video menu and select "direct stream copy", go to streams>stream list and click "add" and load your wav file. Right click the audio and select "full processing mode", right click again and select your compression settings. The last thing you do is save in the file menu.
