Easiest way to bulk replace ac3 streams w/.mp2 streams?

[miamicanes]

OK, here's the scenario: I have a dual-layer disc with a damaged .vob that I'm trying to salvage by re-authoring the most important parts to a new disc w/DVD Movie Factory 2.

I managed to rip all but 2 of the tracks (47 total) usingDVD Decrypter in IFO mode in both stream and non-stream modes, so I now have one directory with 47 .vob files with a video stream and an ac3 stream, and another directory with 47 pairs of .d2v and .vob files. The catch is, DVDMF2 doesn't like ac3, so they've ALL got to be converted to .mp2.

Is there any eay way to point some app at the directory and tell it, "go through all the files, convert the ac3 to wav, convert the wav to mp2, then re-multiplex the resulting file back into the .vobs so I'll end up with 47 files that are ready to burn?"

This might work.

get besweet, follow the guides on using (for one file) it until you get to the point where you are about to press go. Click "copy command to clipboard". Now open a text file (in notepad) and click paste. Copy/paste the line as many times as necessary then change each line appropriatley so that each file is processed once. save this file to your desktop as 'change_audio.bat' (or whatever!). Now simply double click this file, sit back and wait.

Hopefully this or something similar will do what you need.
