This morning I pulled my 8050L apart again to determine where pin6 & 8 go (on the AN22023 mediatek chip).

on the 8050L, for the AN22023:
pin6 === pin 9 === ground
pin8 === pin 41 == TP515 (also goes to uC33 and uC16)
Looking at the 8163b, for the AN22023:
pin 41 === TP515 fortunately, same nomenclature as 8050L.
I haven't cut my traces yet, but I'm going to soon. With Tiros' suggestions, this is what I'm going to attempt:
8163b:
A. pin6 (dvd power shown below) ==== 1kohm ==== TP126
PINK READYB. cut TP126 trace, side that leads to AN22023, obviously
C. solder pin 6 (AN22023) to ground.
D. pin5 (dvd power shown below) ==== 1kohm ==== TP128
ORANGE TRAY_OUTE. cut TP128 trace, side that leads to AN22023
F. solder pin 8 (AN22023) to TP515.
G. pin 4 (dvd power shown below) === EJECT
H. pin 7 (dvd power shown below) === 1kohm ==== TP055

RED TRAY_INI just had another crazy idea, that I'd like to try, but I doubt it would work. The idea is to short LDCD to LDDV, possibly telling the drive that when you load a cd-R, it may fool the drive into thinking that there is a dvd inside. Well, its just a thought...
