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!"
You know what? No one has won until the other one gives up, which I don't see happening anytime soon.
Don't forget that Universal and Sony who is blu-ray's biggest backer are competitors in the movie industry. Universal has no stake in blu-ray winning. So why would they want to support a competitors format when they can support a non-competitors format?
It's pretty simple really. Neither format is selling enough movies right now to make switching for financial reasons an issue. Not even close. So why would Universal switch now or anytime soon? They can always wait and see who wins. If blu-ray wins then they can switch then. Just my opinion, but what do I know anyway?
