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!"
The IMG update came to New Jersey between Wednesday and Thursday. I only realized it because I happened to be awake at 4 am when my FiOS set top boxes simultaneously rebooted a few times. Rather than interrupting them to see what was up, I went back to sleep and checked 3 hours later to find most of the aforementioned features. There are new widgets that tell you what other customers are watching live, and VOD. Plus, there are news feeds, but I don't think there is any means to choose content. I haven't seen any ESPN widgets, nor have I tried to stream HD content yet. I did notice that there are new Guide filters that allow you to see what's on based on pre-determined criteria like Kids Shows and Sports. It certainly trumps Comcast's Guide.
