I have a TIVO with only an OTA antenna. The TIVO is hooked to the Revue and then to the TV, all via HDMI
It all works wonderfully. I can control it all from the logitech keyboard that came with the Revue or from my Logitech Harmony Remote. The Revue controls the TIVO by way of an IR Blaster. It blast a stong IR signal. I mounted it outside the cabnet and 2 feet above the TIVO and it still never misses.
I also have a Logitech DiNOVO Mini and it controls the Revue. (doesnt do well with the TIVO though)
So I leave the large keyboard over at my desk (I can still see the TV) so I no longer have to chase a remote.
The Revue keyboard also controls the volume and power on myPioneer AV Reciever.
After buying the Revue, I dumped my Media Center PC and almost never use my Blueray player any more. Only for DVD and Blueray. With all this, who needs cable...
