I really wanted a mini for my shack in the backyard, but I do not have a 4-tuner Tivo.
The $250 price (with lifetime) was reasonable, but unfortunately it would be a lot more because I would have to buy a new TiVo as well.
I started looking around and found an HDMI wireless transmitter:
This is $150 and *generally* has the range that I need. Watch the video to see some of the issues that I am still working out..
But once that was installed I realized that the IR transmitter in the unit does not work because Tivo uses a dual-band IR. So I had to get one of these:
The net price is ~$180 for the two devices and it took only a few minutes to get them working together (once I had both).
The picture is less than spectacular (even though I am getting 720p) there are some blotchy artifacts that I get from poor signal. I think that possibly getting a longer cable and moving the shack unit off of the TV and onto the wall closer to the door might be good.
The Tivo has dual HD outputs (HDMI and component) so I run component to the TV and HDMI to the broadcaster. HDMI has its own set of issues with handshakes and there are still some things to work out there, but generally everything is working like I need it to.
Here is a video that walks through what I did:
I think within a room this would be great for hiding the Tivo and having a TV mounted on the wall.
