Thanks. I could purchase the Xfinity IR extender (Cox no longer provides for free) but as I understand it, I would lose Voice Commands which are RF mode only.
I get excellent range with the RF remotes I now use with DirecTV but their tech is getting old. Cox was smart enough to make a deal with Comcast for this cool voice technology. with Netflix and Amazon seamlessly integrated. I'm in TV heaven when I'm at my Florida place :)
By the way, I left Cox in 2000 when I got a Plasma TV and called Cox for HD. The rep said "what's that?" I called DirecTV and had an HD Receiver the next day. Of late DirecTV has unfortunately not innovated any longer.
