This issue turned into a 7-page thread at the time! (

If you've never used AnyDVD, download the trial version at
http://www.slysoft.com/en/download.html - this seemed to rip it fine for people that used it. I couldn't because my trial copy had expired. Anyway, this is what you should use if you can, otherwise, it's kind of a pain.
Here's what I did:
-Launch the app and click the green check mark in the upper-right of the window. This will display the settings. Click on "Pathplayer" and select the "Disable Pathplayer" radio button. Also, disable the Preview in General>Preview by un-checking "Show preview window automatically". Save settings and select "Main Movie" in the DVD to DVD window. There's a mess of chapter options. Scroll down to chapter 47 and select it. Select what audio/subtitle tracks you want and make sure "DVD9" is selected in the drop down menu towards the bottom of the window.
-Click Next and go for it. There's going to be an error message soon after it gets going. Click "Ignore" and let the process finish. For some reason, when it was finished, it prompted me for a blank DVD so I hit Cancel and found the .VOBs in the My Documents\DVDFab\Temp\MainMovie folder.
It's not over. There's also an audio sync issue that needs to be addressed. I'm not sure what you're using to do the re-author, but here's what I did to fix the audio:
After you rip the VOBs and AC3, convert the AC3 to WAV using BeSweet/BeLight (or another conversion app of your choice), open the WAV in Audacity (or another audio editor of your choice) and add 2 seconds of silence at the very beginning of the track (Generate > Silence in Audacity). This will change the duration of the track from 02:29:52 to 02:29:54. Finally, export the WAV and convert it back to AC3.
