i've got one, as well as the media center remote keyboard from Micro$oft. both devices work, but the button functionality is pretty limited. i've not found a way to get MC to 'learn' from this unit. BUT I would LOVE LOVE LOVE to get a plug that is compatible with, or specific to, the MS MCE hardware devices (IR remote media keyboard AND/OR the IR remote control).
About 6 months back, I was giving MS MCE, MC, MediaPortal and TVedia a head to head and i thought i remember getting a plugin (i think the USBIR plugin) to work and learn in MC, but I might have been sniffing glue while evaluating the apps.
recently, i'm seeing more and more people ask about this device and interop with MC. so...i suppose its time for me to lay off the krazy glue and whiteout while computing
<sniff, sniff>,
