hi friends, I could use your help! My friend just gave me a DVD copy of a show that we were in together, and I was so excited to watch it on my iMac, but when I inserted the disk it made some noise for about 10 seconds and then ejecting the disk - no icon ever appeared on the desktop. I've tried the DVD on a pc and in a DVD player with no luck - theres clearly something wrong with the disc - but I was wondering if theres some clever way to force my mac into exploring the files on the DVD. Any suggestions? Thanks so much!
