I recently installed a DL SuperDrive into my computer and want to watch my DVDs on it. My 10.3 install disks are on CD-ROM so DVD Player was not installed on my computer. Going onto Apple's site, I had 2 options to download, DVD Player 3.1.1 or the 4.6 Updater to Player 4.5 (which says it requires Tiger so that's automatically out). I download and install 3.1.1 and when I click on the application, it bounces once in the dock and stops. I restarted the computer, retried and had the same issue. So I'm guessing for some stupid reason, it's not compatible with something in my computer (Digital Audio G4). Any ideas? Is the fact that it is a dual layer drive an issue?
