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!"
Whats neat is anyone with a fairly recent pc can pick up one of these and connect them to a Vista based machine and they automatically install the drivers etc. Plug in, ready to go and start watching movies. Provided you have playback software like windvd or vlc player for free.
You can even borrow movies from friends with the 'right' software and 'back them up' for your friend should his hd-dvd become damaged...assuming you have 30gb of space free per movie. Still though, wouldn't 'expire'.
Not just Vista.
They work very nicely with a Windows XP PC too.
I just sold mine after a having it as a ROM drive for a year (for £80/$160 too!).
I might just buy another one at those kind of prices.
