Yep, got latest version, disc is unmarked (and I've cleaned it). Have problems with Shrink as well, and I've used the latest Decrypter to rip it to the HDD. It would not play from the HDD either.
Just tried it on a laptop at work, using Intervideo player and it plays fine. I've tried 3 different programmes, 2 different drives in my PC, with the same result, so it's pointing to a possible hardware conflict?
I've done quite a few DVD's and never experienced any problems before, this one is quite perplexing. (I'm running a P4/2.8, Asus mobo, 1gig ram, Liteon 165, Pioneer 106). Just prior to this disc I did a couple of others (Fawlty Towers and The Mouse that Roared) and they worked fine, so there appears to be "something" about this disc that my hardware doesn't like.
