I'm also confused over RPC1.
MY NEC 2510 was patched with the RPC and Riplock version of the 2f7 firmware found on the dangerous brothers site.
Both DVDInfo and Driveinfo say the drive is still Region Protected.
However, DVDRegionKiller which I have running tells me the drive is region free.
Is DVD Region Killer 'confusing' the other programmes, or is my drive incorrectly patched.?
Also, when burning a DVD, I notice the speed is 4.1x for approx 20% of the burn, increasing to 6.2x up to approx 50%, then the last leg is ran at 8.3x. Is this normal ?
