Extraido de X-box-Scene:
They switched the Xbox DVD drive with a Pioneer DVD-105SZ.
The drive was put in slave mode and they used a splitter from the HDD powerconnector to power the Pioneer DVD-105SZ. (xbox DVD powercable uses a special connector).
All dvd-r, dvd-rw, cd-r, cd-rw worked , and even faster then with the original drive (the Pioneer DVD-105SZ has a faster read speed).
So all people looking for a solution to read any brand of cd-r's can try this trick.
Only downside : the xbox will not read original xbox games anymore & you need to power off the console to change game/disk. (eject doesn't work)
Segun dicen no esta probado a ver si alguien lo hace
