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!"
BOTH formats have DRM. If HD-DVD TRUSTED it's users there would be NO drm. Plain and simple. 1 or 100 levels of drm DO NOT MATTER you are not trusted by either group. It just plain STUPID to say otherwise, I'm looking right at you xyzzy.
An extra level of drm won't be an issue for people making the dvd rippers. It will actually be a bit more fun. Since there are so few players right now and most can be software updated I don't sense this as being as big of an issues as the fact that
BLUERAY is now finalized. All players from here on out WILL be comatable and the studios can finally fully support the format.
