Cheule, you are absolutely right about letting the Apple DVD player have a look first.
Once the DVD player has launched and started playing the movie, you can quit straight away.
This lets the region code be recognised by the OS, as you said. This is imperative to extraction.
Also, I personally use 0SEX to rip the files. I've never tried DVDBackup, but 0SEX seems to do a mighty fine quick job.
After purchasing DVD2oneX, I managed to test rip, transcode and burn a FULL 7Gb DVD to one DVD-R in less than 1hr and 15mins. No glitches, no errors, no problems.
This is what we've all been waiting for for so long!q
