"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!"
yes hd-dvd is inferior as I just came from Home theatre store and they had it set up to a small tv set if hd-dvd was as good as they say then why have it hooked up the way they have it in stores which is crappy
