Has anyone heard of a mini dvd-r drive to go with the 1.4Gb mini dvd-r media?

I know I can burn the disks in my DVD-R and there's a Sony Camera that uses them, but I'm looking for a drive that might fit in a 3.5" floppy bay, or maybe a USB/Firewire unit I could kit bash for a Linux based PSP knock off project.

If not a burner, how bout a dedicated DVD player?
