I have an ibook with MAC OS X 10.3.9. I tried to play a dvd for the first time last night and it would not work. When I insert the disc I can hear the drive attempting to read it and then it simply ejects the disc. The DVD player application does not attempt to open when I insert the DVD into the drive. When I open the DVD player application I get an error that says something to the effect of "Can't detect DVD drive." Then the application quits. Any tips? i tried downloading updates from the apple site but none of them would run on my comp. Appreciate any advice.
