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 still don't get the piracy concerns over component cable issue. I realize HDMI has the protection built into the cable, but why not just have the player check the disc to see if it has copy protection on it? All my old DVDs I copied stripped the protection off it, so shouldn't the player be able to tell if the disc has it on or not? If it doesn't have any not on it, don't play the disc. It's that simple. I guess the pirates could put fake protection back onto the disc, is that the entire reasoning behind it? But wouldn't it then be good for HDMI cables if they did that? I've never understood this issue.
