Thanks very much for that. I Disabled using LtnPRC and got the "PRC Work Disabled" message. But when I check using the EEPROM Utility, it still says the drive is RPC2. When I use the Utility to set the drive to RPC1, it gives the error message "Sorry the region control for this drive could not be set to RPC1". Is this OK? I mean is the drive now region free (with DVD Region Killer running in background).
disable DVD Region Killer. Then check again. discinfo is a simple uitlity to check drive status.
