I don't know if there's any available documentation for the DVD drive's low-level interface. However, I've disassembled one of the dumps and found some tables of CR-terminated serial commands that might be used to control it.
There is also one table of serial commands that is definitely not DVD-related. These pertain to the system's other (apparently optional) serial peripheral, a 3M MicroTouch touchscreen controller. This device has official documentation available, which looks reasonably complete, and an existing MAME emulation of it, which is not very complete.
