Let the hive mind of Engadget get that for you.
"I am looking for a device that will stream sound from one source to several recipients. For example, I want to stream sound from my TV or stereo to my phone or MP3 player that has radio and Bluetooth capabilities. I have looked into radio transmitters and they seem like a decent choice, but I can't find one that uses external power (USB or from the plug) and I would want one with a transmit range of around 50 meters. Thanks!"
Ummmm... wouldn't cable and satellite companies be able to get around this by creating set-top boxes that can pick up and (if they're DVRs) record digital OTA signals? Or would that not fly in rural areas?
My parents have DISH Network, but they don't get local HD signals through the dish, only OTA.
