Hello You all have been so helpful, I legally burned my first dvd w/out anything but mac the ripper and my new G5imac! Now I am trying to burn a new one and for some reason the mac the ripper is unresponsive. I put in the DVD and opened mac the ripper and nothing happens. SO I stop the DVD. I even threw away one version and reinstalled a new mac the ripper but it is still doing nothing.. Doesn't recognize the dvd. What is happening?
