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.)
