JK,
my wife and I love our 890 PRO. We do use the RF Extender and I also control a PS-3 seamlessly. Room lights are controlled by the remote also.

The ONLY glitch I have, and it is not an 890 issue, is that sometimes when I power everything down the receiver sometimes does not turn off. I'm quite sure it's a delay issue that I have been unsuccessful in resolving and I've tried a couple of times to get Tech Support to help. (Tech Support is great, I just haven't solved this prob. As I say, it is NOT a 890 issue - just me being lazy.)
