Hi all.

I read the FAQ section on copy protection, but I didn't seem to find the
scheme that is responsible for the following:

On my linux box, when I insert a labeled copy-protected DVD, I can mount
the volume fine. Trying to read any files on it, however, results in I/O
errors at the kernel level:

Jul 30 19:39:53 jekaterina kernel: [24270.306257] hdc: command error:
status=0x51 { DriveReady SeekComplete Error }
Jul 30 19:39:53 jekaterina kernel: [24270.306263] hdc: command error:
error=0x54 { AbortedCommand LastFailedSense=0x05 }
Jul 30 19:39:53 jekaterina kernel: [24270.306267] ide: failed opcode
was: unknown
Jul 30 19:39:53 jekaterina kernel: [24270.306270] end_request: I/O
error, dev hdc, sector 1536

I know from the label that the disc is protected, however, it is unclear
to me, if the scheme is part of the DVD Video specification. The disc is
clearly marked with the DVD Video logo, so in effect, I am trying to
ascertain if the disc is mislabeled.

Best regards,

Sune Mølgaard
