Up front, I haven't a clue as to what I'm doing with respect
to DVD copying. I can follow a recipe. The one that has worked
has been (1) rip the disc with MTR v266 and (2) compress
and burn via Popcorn v103. I stubbed my toe on (1) today.

I rented a DVD that had apparently been re-done in some
fashion. It was a tad weird. Finder told me the DVD's name
was UNFORGIVEN_4X3_V2, whereas MTR had UNFORGIVEN_16X9_REDO
and would do absolutely nothing useful. I'm used to auto-
magically seeing the disc name atop the MTR pane, but all
I saw was "Mac The Ripper." It was as if the disc didn't
exist. Except MTR saw the title in its middle bar. When
I clicked "GO" (for want of anything better to do) MTR
crashed. Oh naughtyord.

Off to versiontracker.com to find DVDBackup. I have no
idea what that is/does, but I don't have a life and gave
it a shot. Dragging the DVD icon into DVDB gave me a lot
of VIDEO files. I selected them all, said "Do it," and the
app did something. I was pleased to see a VIDEO_TS folder
on my HD afterwards. I dragged it onto Popcorn's window
as Goodwife Bloom yelled "Dinner!" for the umptyleventh
time, forgetting that I should have run that VIDEO_TS
thru DVD Player first. Leslye yells, and I obey.

Ah well. It didn't matter. The copied DVD looks to be an
exact duplicate of the original.

Would someone prettyplease tell me what just happened?

Why did MTR, the gold standard as I understand it, go
belly-up on that disc? What did DVDBackup do that MTR
couldn't? Am I hallucinating?
