BluRay has the better tech and a more forward looking overall plan. HD-DVD is only cheaper for the media companies because they figured out a way to reuse most of the current factory pressing tech. This means THEY make more $$ off of the end user; it makes them appear cheaper out of the gate, but even though they save all that $$ they will not pass it down, they will pocket it. BluRay will be more user friendly when it comes to EULA and fair use, another great reason to back it. HD-DVD does not have more or better backing even as of 2005. This is exactly like beta vs vhs. Do not back HD-DVD (aka VHS) back BluRay (aka Beta). Its time to make up for that mistake.
Beta lost out for 2 main reasons neither of which was being inferior.
1. Media companies were afraid of the superior resolution at the time, thus pirating. (Stop beating this drum guys, you have done so with every new recording tech and the sky has never fallen. You constantly top revenue records every year.)
2. Sony refused to licence its tech to others because of fear of losing control; a mistake they admit and will try hard not to repeat.
