I replaced mine with a Sony DRU-501 drive (does take some handywork for fitting).
A NEC 1300a which I tried first would not work.

Just go pickup an NEC or other Sony DVD-RW drive. I replaced mine with an NEC. It is still picky about media. and does not burn any faster. Sony must lock the firmware of the player not the DVD drive mech.

Partstore.com has this part. It's about $240.
