If you "occasionally would like to watch shows from the bedroom,"

Yeah, that's about it. The distance isn't going to be that much, maybe 35-40 feet or so, but the signal may have to travel through four or five walls (albeit thin ones.) My wireless router is in a third room, and the room that will contain the video receiver (and thus the TV) won't have any 2.4 GHz sending/receiving devices in it.

My Googling for a One-For-All sender tells me it's not available in the U.S. That 900 MHz model doesn't look very current, and the fact that they say "we recommend both be in the same room" tells me it won't do very well in my situation, two rooms and four walls away. I've seen mixed reviews on the X10 model so far. This RCA model has an okay review but the reviewer didn't make it clear what distance is involved. Terk seems to have a few solutions in this arena, including this one but I haven't been able to find reviews. They also have a neat but expensive solution that uses telephone wiring, but I can't remember if I have a phone jack in the room with the TV. Seems phone line might be a nicer option, to avoid interference, at least. One of the Terk models seems to be available at my local Circuit City, so maybe I'll give that a shot, since Circuit City is good with returns.
