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!"

... So, if you don't have an internet connection near your HD-A1/XA1 or, don't want to wait to receive the Update (IDENTICAL to the 'shady' download file) on a CD from Toshiba, ... visit AVS (link above) and download it from RapidShare.
Must admit listening to "The Phantom of the Opera" (only HD DVD I have at the moment) TrueHD 5.1 Track is Most Glorious!!!
