We have an
Iogear wireless transmitter to feed the programming from the livingroom TV to the bedroom. We're not that happy with it because it frequently drops the signal to the bedroom TV. The transmitter and receiver are about 30' apart, and there are a couple of walls in between. It probably would work better if it were line of sight, but it's supposed to work up to 100' through walls.
The signal for the living room TV also goes through the transmitter because there is apparently is an internal splitter, so the living room TV sometimes blacks out for 5 to 10 seconds at a time, too, even when the bedroom TV isn't on. Fortunately, we have a DVR so we can back the program up to see what we missed.
Lots of people here on iRV2 have had success with the Iogear system; but at 3.7 out of 5 stars, the reviews on Amazon aren't that great. Lots of people there have the same problems with dropped signals.
