I decided to make my Mac Mini a HTPC and as such I am making digital copies of all my stuff. My problem is that every now and then I will put a DVD in and it won't spin up and it wont show up in OSX. If I open Disk Utility it freezes. The only way to fix it that I have found is to turn the computer off and then back on in which case it recognizes the DVD and I am back on my way. Any ideas?
