I have an intel iMac with Snow Leopard 10.6.7 Generally, I can borrow a movie DVD from the local store, and it plays, no problem. I have just bought an Australian TV series in an Australian shop (ABC) - I live in Australia, but the disc goes into the computer, sits for a few seconds, then gets rejected. - I have repaired permissions on the hard drive. - I tried firing up Parallels to see if that would help. Nothing. What can I try next? Also, how can I find out what region my computer is set for? BTW, I am not overly technical, so if you say (e.g.) check the PRAM I will have no idea where to start looking for that.
