I don't play a LOT of DVDs, but on, e.g., C6 on the same hardware
I don't recall ever having onefail to play with VLC.

In looking at the source package for libdvdcss, last night, I see there
are 3 different ways of cracking the encryption that it supports. The
default one is to try to crack each file's encryption, with the down-side
that it may fail entirely. there is also an option to crack the DISC's
key which can then be used to decrypt each file. from the description
it sounds as if the disc option might be better even though it isn't
the default.

If all else fails I will try hacking around with that option.

I'll certainly keep that in mind as a fallback position. but I prefer
to  run free software whenever possible, so I'll keep on poking at it
for a while before giving up.

thanks for the idea, though!
