As opposed to DVD-R discs, DVD+R discs do not have the CSS-area pre-recorded (or earlier pressed). The copy protection is located in the firmware of a DVD+R writer.
Because most DVD+R writers are manufactured by RICOH, it could be possible to crack the firmware, so that it doesn’t write the CSS-area automatically. It should be possible, as it was also possible to crack the region codes on DVD-ROM drives and some standalone DVD players.
That way, we could backup DVD movies without the time consuming decryption of CSS.
One example scenario would be:
- I copy the movie with a clone program, but the CSS area is not written on the disc - The disc will not play in a standalone player
- I use a specialised program, that will read out the CSS of the original disc and write it to the +R
Any comments on this?
