Basically since I installed leopard (nearly a year ago) I've had troubles with my DVD playback, as well as burning CDs. DVDs pause and stutter and are unwatchable. DVD player was worse, but VLC is still damn bad. IS there actually something wrong with the drive, or is there actually a problem? Anyway to fix it? It seems ridiculous that I can't watch DVDs on my fancy mac when I could on my 5 year old £400 pc.
