Yep I'm sure my DVD-ROM drive is checked in
AnyDVD. It's probably my Windows installation is screwing up. I will get a new hdd sometime this week and will try again after a fresh Windows install. Will keep you guys posted on the result. Hopefully the problem goes away.
Btw I thought DVD Region Killer (Elby's) and AnyDVD work differently. I may be wrong, but I thought DVD Region Killer simulates a RPC2 drive for RPC1 drive while AnyDVD simulates region free disc.
