So I was trying to copy a DVD I put in my imac that I recorded on my video camera. I hit the COPY DVD and its working, but its saying its going to take up over 2GB of space for a 50 minute recording, & there is no cancel option! I'm trying to cancel the copying process and it won't let me. The Red X in the top left corner is grayed out, and there's nothing on the top menu options. Why is this happening? I thought it was supposed to be easy to put your DVDs right to the hard drive.
