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!"
derek above says that 1080i HDMI looks as good as component. Bill Hunt mentioned that he was trying 1080p. Now I've heard that this player converts from 1080p (for 1080p encoded discs) to 1080i, and then back again to 1080p. Maybe it's this 1080p conversion that's causing the quality loss, not the hdmi output itself? Just a thought.
