Anyone out there know about screwy DVD/CD players on Powerbook G4's? Mine was working fine until recently it began pausing during movies, and sometimes quitting altogether, explaining it as an "error it could not recover from". Also, about half the time now, if I insert a DVD, it spits it back out. Sometimes it helps to shut down, or put it to sleep and then try again, but not always. Also, I am trying to burn a DVD to backup my data and it keeps quitting saying there was a "sense" error. I just ran Disk Warrior and cleared up directory problems. This is my only real line of defense when it comes to fixing problems on my Mac. Any suggestions?
