I have a Mac mini, from December 05 (pre-intel, obviously)....for some reaosn, wheenver I play a DVD, despite cleaning it really good, the player will freeze and stop saying an error occured after reading the disc and it cant recover from the error. RIGHT after this, I will put the SAME DVD into my PC and it will play the whole way through without any problems..........this happens ALL the time. Why is this? Is there something I can do to correct this so I can just use my Mac Mini? I don't get it.....there's no scratches on the DVD and it plays fine on my PC so why won't it play on my Mini without freezing and stopping?
