Error cracking CSS key

[Greg Kilfoyle]

Hi,

I'm trying to access a PAL DVD from Linux, but I'm having problems.
Using ogle to try and view the DVD I received the message "Error
cracking CSS key". I then looked in the archives for this list and set
DVDCSS_VERBOSE=2. The following output was the result:

This DVD plays fine under windows using the same DVD drive. It also
plays in my home DVD player, but the TV loses sync (because the TV is
NTSC).

I've successfully accessed another PAL DVD using Linux with the same
drive, so this problem is particular to the DVD.

Thanks, Greg.
