I hope this structure of the "thread"doesn't become too complicated....the subject itself is already tricky to comprehend (for me too)
I guess the protection functions CPPM and CPRM work hand in hand with eachother I don't know yet how far the CPPM protection is having it's influence, also on plus media ?
CPRM seems to have it's reach only over minus media,
i guess because it's the media that mostly complies according
to the original DVD video "book" specifications aka DVD consortium.
Using PlextoolsProXL 3.07:
With the PX-740 from Plextor, with the 1.01 firmware,
some information can be read, from a disc recorded in DVD video-recorder, that only can use -R and -RW media for recording, with the 1.02 firmware in the PX-740 the drive is still CPRM compatible but now it can read the complete DVD video disc, and make an image to make multiple disc copies from, but all these discs are still not seen by the MS Windows Operating System.

btw. trying to make a disc of the image using a +R type of media, fails...

btw2. The CPRM function is also designed to work on SecureDigital memory cards, or transferal over a Firewire or iLink connection, also the protocol is ATA friendly

but the designers say this will not be used as such....?
You can do a (Goolge) search for your self on the CPRM subject, but you will not get happy doing this

Old read and burn hardware seem to be the most safe option to defeat CPPM/CPRM.
The hardware Manufacturer is free to build (or not) in this CPPM/CPRM function, unlike the MacroVision protection,
which looks much the same, in it's mechanics..
