Apple's DVD Player will only work with internal DVD drives and will give an error -70012 if you open it with only an external DVD drive attached.

I had purchased the captioned DVD player about three years ago and the player has performed admirably up until a few months back - when on an ad hoc basis it started giving the C 13:00 error message.

Whenever I open Snes9x for the first time and hit Load game I get the following event viewer error:Application popup: Snes9XW.exe - No Disk : There is no disk in the drive. Please insert a disk ...

However, the DVD player started working once I removed the iXMicro video card (installed but not connected to a monitor) from my G3/300 upgraded to a G4/450 with stock ATI video.

If you encounter error A device which does not exist was specified, when you open a disk in Explorer or try to initialize a disk, see this post.
