Computer rejecting (almost) all DVDs.
I got my MacBook Pro back in July and until the whole SuperDrive Update 2.1 thing, it never had any problems. Since then, and especially since I installed Leopard, it's gone downhill. The computer runs fine, and it takes CDs 100% of the time, but DVDs are another story.
I've tried many different movies - very few work. The Leopard disc won't mount either. In each case, I put the disc in, it whirrs around quietly for about six seconds, clicks a few times, whirrs for another six, and then spits the disc out.
I saw the SimpleFlash firmware thing in a previous topic, but I could not get it to work. Any help would be appreciated - I'd rather not have to send my computer back to get the drive replaced, and that might not even solve it anyway.
MacBook Pro, Mac OS X (10.5.1)
