-Is there an app that can check a VIDEO_TS folder on a HD to see if it will need to be "fixed" and if so can this program also prepare the files in the VIDEO_TS folder so that they can be burned with any DVD burning program (like Toast or Nero) without any further changes being made?

am I onto something or is this just wishful thinking?

Paul, have you ever downloaded a DVD and burned it with Toast and found no errors introduced?
This thread is getting somewhere, which I can't say for the same attempts to make some sense at videohelp.com Apple Discussions or at the Roxio forums... :-)

Yes, many torrented DVDs have been burned without anything changing. Typically the "authored by me this and that way" kind of DVDs. It's usually the "i got this in a trade by some guy" DVDs that has the .ifo and .bup files changing.

Example: All 3 DVDs in the Pink Floyd Anthology DVD set was shared at EZT. I burned them all without errors or changes to any files. Great. Then I went to the Harvested-weeds site and got the MD5 files posted at the site and compared. Everything checked out OK except for the two .ifo files and the two .bup files of disc 3 only. Disc 1 and 2 was a perfect match for all files, so the seeder obviously had good copies.

Now just out of curiosity, I downloaded Disc 3 again and checked. The files in question did not match the "official" md5, but it's a good copy and Toast ket the files pass without "correcting" anything. Strange thing.

But sometimes I get a DVD from a torrent that doesn't get corrected at all, and when played there is a pause at each chapter break. My guess is that it's a badly authored DVD or something and nothing to do with what we're discussing here.

So yes, I think you are on to something. But what's the final word? I don't know.
