I bought Friday the 13 The Series and everything was fine till i got to disk 3. The third disk till the sixth one will not play on either my DVD player or PC. When I try playing it on the DVD player I get sound but no picture. The PC tells me there is a problem with copy protection and to try to update drivers to fix the problem. I plan on returning the set tomorrow but just wondered if anyone else is having that problem or if I just a bad set of disks?
