Copy protection issues with backing up a DVD

[Bizzen]

I'm trying to backup a movie with copy protection using DVD Shrink and it doesn't work.

DVD Shrink analyses the files as normal but when I click backup to create an image on the hard drive as I watch on the display it just gets stuck more-or-less straight away with a 'cp' logo on screen.

Any ideas? Will switching to another piece of software solve this problem?

This is the first time this problem has occurred. DVD Shrink has always worked flawlessly up to this point.

Try ripping with DVD Fab Decrypter, and then shrinking with DVD Shrink.

Ah, Here we are. I wonder if this is actually another cute trick (of two I have not seen any info on here).

Trick one is embedding deliberately bad sectors in the VTS_##_01.VOB file (where ## is the main movie file). This is not a physically damaged sector, but one that was written with a deliberately incorrect CRC. The IFO file tells the player to skip the bad sector(s).

The second is trickier. The video plays with jerks back in time about half a second at one second intervals (which, I believe, is the length of time between B frames). This seems to be something in the one or more langauge(s) on the disc, if any. They stream the file data with out of order frames and since not one program I've used can properly use the IFO files to play the VOBs back the same way a DVD player does (standalone hardware or PC software based), you get these jerks.

I have seen this on several new release DVDs from the house of mouse (since they apparently appropriated all output from Gibhli) such as Howl's Moving Castle, which I really want to load into my Archos Portable for use on overseas flights and such.

Run AnyDVD in the background then use DVDShrink ...

ryukurai, I think you are reading too much into this. If the poster was using DVD Shrink by itself, there's no surprise that newer DVDs may require more to decrypt them. DVD Shrink will not be updated anymore and there are newer encryption methods such as Sony ARcoSS. DVD Fab Decrypter handles this well, as long as you use the latest updates.
