For what it's worth, I have the Matsushita drive in my Pismo and it has worked fine.  I don't know if there are, perhaps, different revisions of the same drive, but Apple System Profiler gives the Revision number of the drive I have as Revision C113.

LEM sez that "the OEM DVD-ROM drives were prone to early failure."

IIRC, the pink screen you refer to is a sign that your backlight is on its way out.  This seems to have been a problem with some Pismos that developed the problem while still fairly new, but if I understand correctly, it's a problem that all Pismos will develop over time as they age.

The Pismo I'm currently using (purchased used) seems to have developed this problem recently. :(  Granted, it's a decade old, and eking a decade out of an LCD doesn't strike me as doing too badly, but I don't know if that's widely considered a reasonable service life for an LCD or not. [shrugs]
