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!"
ABC was best for me. Great picture and minimal graphics. CBS was second, same picture, but way too garish graphics. NBC and HDNet were just a little soft compared to ABC and CBS.
Fox was crap. I switched between the HD Fox and the SD Fox channels, and the SD Fox looked better.
I can't comment on the audio since I had it on mute the whole time. Just watched it for the HD comparison.
