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!"
I have Comcast VOD also, it's so annoying how little HD content there is in there. Before I had an HDTV I used VOD quite a bit but now that I have HDTV and 99.999999% of the content is SD, I rarely use it. And everytime I do I check the HD section, hoping that something has changed.. usually they've added a movie or two and taken away a few others. :( The only good thing is that most of the HD movies are usually free of charge. But considering they only have 1 or 2 new movies a month, it's pretty crappy.
HBO lost my business because they dont have HD on demand, they haev an HD channel with tons of HD shows, but none of the on demand stuff is HD. Too bad for you HBO, I would have gladly kept paying your outrageous $16/month if you had HD on demand.
So this news is very good to hear! Hopefully they follow through. :P
