"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!"
Agreed, this is totally ridiculous. I already paid for the movie; I'm not going to allow movie studios to bully me with the DMCA into thinking I'm obligated to pay for it again. I purchased the disc; therefore I see myself entitled to use the content on it as I see fit.
Dear Blu-ray and the clowns behind AACS: take your broken copy protection and "managed copy" and shove it. In the meantime, I'll be using AnyDVD HD to backup my movies to my media server and stream them to my HTPC.
