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!"
This is the kind of stuff we need. OEM support of a blu-ray/dvd storage HTPC. Yeah you'd still have to install some software to rip those onto the hard drive I bet, but once it's there this should play it all back just fine. That and lossless codec support would make this something worth saving up for.
