The Schmartz PS3IR-1000 arrived yesterday. I'd suggest this device to anyone who wants to use their PS3 as a BD player in a LinuxMCE environment. Nice device - very easy setup, very small size (about the same as the USB-UIRT), comes with a simple postcard size directions sheet with everything you need to know to get it hooked up and paired with the PS3. I popped it in, got the pronto codes from the website, made a new template, and it "just works". I had no need for the Windows-based software that they distribute for it.
The template should also work with the PS3IR-500 since they use the same codes, but you will lose the power sensing features for discrete on/off (remember to also buy or make the power sensing cable if you want that functionality - it is NOT included with the device). I didn't program in the game play codes (triangle, square, circle, cross, start, select, PS button) into the template, since there's no matching commands, and no spot for them in the UI. It might be funny to play a game using the Orbiter as a controller, but probably not too useful.
Since the PS3 starts playback/gameplay immediately when you insert a BD/game, I'm not having any problems getting what I want on the screen. Also, the BD and DVD remotes on the Orbiter each have menu navigation, so you can move around the PS menu manually if you need to. There is no easy way to have a "watch movie now" button, and it doesn't seem too useful - so I'm going to let it go.
I'll let you all know when this is available in sqlCVS.
