Just got the Cube and so far I like it, I'm using the K700 keyboard from my Revue and run into a weird problem. I can turn the TV on and off with the keyboard but my Yamaha HTR 4064 I can control the volume but not the power. If I hit AVR on my K700 it powers off the TV instead (the TV button on the K700 also powers off the TV). I also noticed the TV/STB button on the Cube's remote doesn't seem to do anything when I press it (it doesn't send out a IR signal when pressed either). The Revue controlled my receiver with no problem though it was also listed in the setup which the Cube didn't show.
