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!"
a) Blu-ray players cost twice as much as HD DVD players, many brand more so.
b) most movies look better on HD DVD, best Blu-ray "look as good as HD DVD". No Blu-ray movie looks better than an HD DVD one. If the best it can do is look "as good" why pay twice price?
c) Blu-ray has region codes, anti consumer practice to keep prices high in places like Europe and UK. HD DVD has no region encoding, you can buy discs from anywhere.
Meaning many "Blu-ray exclusives" are only exclusive in USA, buy the European HD DVD version on the internet instead. :)
d) you can burn your own HD DVD discs with a regular DVD burner in your PC/Mac, 4.5GB and 9GB DVD can be formatted as HD DVD and used for playback of TS files. Archive your HDTV shows to HD DVD format, today! Blu-ray isn't so "enthusiast" friendly.
So how is Blu-ray better and cheaper?
Your B and C points are wrong.
A: The Blu-Ray players are better thats why more expensive.
D: There are no PC/MAC burners while Blu-Ray have more than 10 different brands ...
