The DVD player on my home theater set-up decided to stop working so we decided to watch a DVD (from Blockbuster) on the new MBP. Really the first time I've used the drive, so was curious to see how a full length movie looked on this screen. Anyway, noticed the DVD was pretty smudged and scratched but went ahead and put it in. No problems till about 5 minutes into the movie (Barbershop 2, don't ask, my wife and brother-in-law wanted to see it ) then the screen froze and the system locked up. Completely unresponsive so I hit the power button to trigger a shut down. Computer booted back up fine. Ejected the disk and wiped with a lint free cloth, then put back in. Movie played from beginning without issue -- no freezing or anything. I'm now worried that I've done something to the drive. 1. Could I have damaged the drive by doing what I did above, given the movie played fine after wiping the DVD down? I'm assuming it's probably best to avoid putting discs like that into the Superdrive in general? 2. Is there a way to run a diagnostic on the Superdrive to see if it is working properly now? 3. Am I blowing this out of proportion? Thanks in advance.
