I'm a newbie and experiencing the same message with the Sony DVD/CD DVP-NC80V player. From all the searches done, there is not a method to reconfigure to R0 with the remote or firmware.
The discs are from Greece and are R0 (no RCE, CSS file) as reported by DVD Decrypter. Also, I use the current version of DVD Shrink.
Copying only the main movie, when placed in the Sony, it will not accept the disc.
What I find interesting, my un-hacked 2 year old Apex AD-1200, R1, $29.95 from Sears, plays these discs.
Yes, I can move the Apex to the living room and plug into the receiver. However, I'm attempting to learn more about DVDs and would like to eventually solve this problem.
Suggestions will be most welcome -
