Best way to extract from DVD?

Well I thought this was going to be easy with 6.0d but it looses a few frame of A/V where the VOB break is. I'm guessing there's some nasty bit of code out there that'll do a reliable job, trying to wade through places like VCDHelp is difficult to find what really works and what doesn't.
In the interim I'm doing it the old fashioned way, capturing from DVD player.
Oh and in case anyone wants to know, the parrot is back in his cage. The purpose of this is to redo the vision on the reviewers copies with serious supers to prevent copying, seeing as how it's neither possible or economic and rather pointless anyway adding DSS, this should stop the slime balls.

Ooh, that always makes me wince. Just shouldn't have to do that. So slow, and the quality is lost.

When Vegas chokes on VOB files (which it often does) I've had 100% success using Womble to simply send the VOB to an MPEG-2 file and then importing that. Better yet, in many cases where I simply want to combine content from multiple DVDs, I just put all the VOBs on the Womble timeline, cut them up, and send out to one single MPEG-2. I then put that into DVDA and away we go! Takes only a few minutes, and zero quality hit.

Thanks John.

Problem is I've got to add this super over the image.

Vegas copes OK with the vision and the mpeg audio much to my surprise, i's just a few frames either side of where the VOB files join. I suspect the GOP isn't closed or something like that is spinning the decoder out, probably if all the files were joined as one data file all would be well.

As to the quality hit, these are just review / sales copies.
I could tell you how many commercial DVDs have been made by dubbing from a player and they didn't even bother with S-Video, and they were converted using a $100 NTSC to PAL box, YUCK.

If I was doing this in ernest I'd demand the master tapes, the director / producer isn't to much into the technical stuff, he had the editor add a super, it's in the black area from the letterboxing, now that'd be hard for someone to remove.

You could try using something like DVDDecrypter to extract all the 1GB VOB files to a single big VOB.

If you're correct (as I suspect you are) that the problem occurs at the splits between the various VOBs this should sort it out.

I don't know why it works sometimes and not other times, but what I do is import the vob file into the media pool then let Vegas re-build the audio files. Then I drag it to the timeline and render to avi. Then I edit it and render it to whatever. Works every time for me, but sometimes the audio is truncated and not equal in length to the video so I have to do it over. Try rendering to uncompressed avi if that happens.
