Got a strange issue with Handbrake. Bought a new Macbook Pro in December. 17''/ 2.53 Ghz i5 / 4GB ram. Handbrake installed (Version 0.9.5 i386 (2011010300)) DVD drive is locked to R2 at the moment. Rips R2 discs no problem but Handbrake just locks up halfway through scanning any R1 disc. Now I know the first response will be 'Your drive is locked to R2' but so is my other macbook and it rips R1 discs no problem! Is there some setting somewhere hidden in Handbrake that I need to switch? Can't work out why one macbook has no problem but the another macbook does.
