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!"
Yeah, I'm confused too. I've always been able to receive HD locals on 81, 83, 87 and 89. But I've talked to DirecTV a few times and they say I shouldn't be receiving the channels because I live in an area (Northridge, Los Angeles, California) that has over the air high definition. I even had someone else out to take a look at some problems I was having and he told me I couldn't receive HD, even though I was walking a college football game in HD on ABC 87 on my 61" TV. If you've ever watched football on a 61" TV, its REALLY easy to tell the difference between HD and SD. So what gives? Are they wrong or am I? Also, I don't need to do anything with my system to receive the new channels, right? I have the HD Tivo and don't want them to take it from me!
