Whats up? I am a new guy to the site, but not to mac. I have used macs for a few years. So my question is, I make backup copies of the dvds that I own and store them on a hard drive. I get some dvds that says it has bad sectors, 1 what is this and 2 how do I get around this. When it tells me it has bad sectors it says it wont play, well I tried to play them from hard drive any way and it wont play. So what can I do to fix this problem?
