I have an iMac G4 800 / 256 / 60Gb / Superdrive, running OS 10.1.5 (waiting for Panther). I have not previously tried to burn a DVD but have produced music CD's without problems.
I created a slide show album with background music, which works fine in preview but when I try to burn, the button appears to start the burn, opening and spinning slowly for about 10 seconds, a little faster for about 5 seconds and then stops and closes. I hit burn again and same thing. Tried to eject the disc but could not. Closed iDVD and got a message asking if I wanted to burn to disc! Hit Yes (or Burn?) and away it went, making the right kind of noises. I ended up with a disc that appeared to have been burned, but nothing on it when double clicking the icon, and of course, nothing plays. Does this sound like a software or hardware problem? I'm using iDVD 2.1 and the disc I tried to burn is a x2 speed.
