Interested to know if you got the ps3toothfairy to work with your MX-900. I've got an MX-880 with an MRF-350 basestation that I'd like to configure it with. The site says to use PS2 codes if there is no ps3toothfairy code set already in place. I want to have a solid plan in place before I buy so I know what I'm getting myself into. I had an IR2BT but it just broke down on me. I liked it, but if I can get a power down macro that actually works reliably I would gladly hand them over my hard earned cash!
