new 27" iMac 2.93 10.6.4 out of the box. didnt update it as I was presuming it was already uptodate so I had already installed Handbrake/VLC 64bit latest versions. DVDs play fine and instantly in the DVD Player App, however when opening a DVD Disc from the SuperDrive in VLC it takes forever for it to even load it up, just the loading bar. Same with handbrake, I went to scan the source straight form the SuperDrive and have been watching it sit for over 30minutes it wasnt even scanning it just said scanning source but no progress bar or anything. However in my MBP 15" the discs play instantly in dvd, vlc and scan immediately in Handbrake. any reason why this would be?
