I'm using an MX-950 with a PS3 per Daniel's instructions
here. The PS2 remote and IR receiver can be had for less than $10 and the Radio Shack PSX-to-USB adapter is about $12. No On/Off controls, but you do get full control over BD playback.
Damon, the BDP-S1 codes were just added to the IR database (Ver. 1.79).
