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!"
I agree, there is nothing wrong with Watermarking. i am not infavor of people illegally sharing via p2p. but i am in favor of being able to watch quality programming via web, disc and directv.
if watermarking will allow us to enjoy more programming without HDCP content flags, no problem from me. i just want to be able to watch, dvr and backup onto disc
