when the time comes that blu_ray dvds come out, dvd players will most likely be able to play both blu_ray and normal dvds, as I'm sure there would be a consumer back lash if they didn't, all it would require is 2 different laser reading mechanisms in the dvd player. I believe current dvd players use a red laser. If you think about it, most people use dvd players for cd players as well, which uses a red laser, so it would be wise for dvd player companies to incorporate the reading of cds/dvds/ and any new dvd formats. The blu_ray discs just use i believe a blue laser which has a smaller wavelength allowing more to be written onto a disk with the same physical dimensions.
There are things about what dvd player companies will do when the time comes that they upgrade to blu_ray discs. I'll look around for them later, but for now, back to physics.

on a side note that 25 gb paper dvd by sony is interesting.
one more link... good amount of info. http:// http://timefordvd.com/tutorial/H...ial.shtml
what is interesting would be how they build the new dvd players, since blu-rays disks have to currently be in cartridges, till they get a better scratch resistant coating. From what I've read its pretty much you get a scratch on the disk and the disk is as good as done for. They'll prolly have to sell empty cartridges to which you would probably just need one, then put one of the old dvds in any time you want to play it. Personally I kind of like the cartridge idea better.
