It seems like the movie industries are sitting on the fence, backing both... something these press releases forget to mention.

If we end up having to buy *2* different media playing devices to be able to watch all the movies we buy, I'm going to be pissed off! :evil:

This might be a good place to discuss the 2 formats. Can we expect to see a burner that will burn both formats as well as DVDR/RW ?

Can we likewise expect to see players that can handle all the above?

I'm not sure of the differences in the physical specs... it's hard to say right now how hard it would be to make a dual burner/reader. Probably the reader would be much easier I would think.

HD-DVD and Blu-Ray have different numerical aperture (0.65 and 0.85 respectively).

In short:

http://www.blu-ray.com/faq/#3.2

There are other differences however, namely in channel coding, rotational speeds, pitch, read-power and several margins. And that doesn't even touch on the media format issues (or logical formats).

I'm not an expert on the issue, but I haven't even seen an optical pick-up head that supports both formats.

More than likely it's possible to make one, but at this stage of the format battle, I can't see either camp being really eager to support such an effort (?).


However, if neither of the formats really fall on their face and die away quickly, then I can't see any other possibility except there being universal players at some time in the future.

It took a long time for dvd-a/sacd players as well, so it could take a long time for hd-dvd/blu-ray recorders/players.
