I fully agree with you. Most people buy DVDs because many stores don't carry vhs anymore and they don't care about what features their DVD player has like progressive scan. People are forced to buy a DVD player... probably just buy the cheapest one (the 30 something ones from walmart) and that's a pain for them. The mainstream won't even  think about bluray because of the price.

Thats why HD-dvd has a much better chance of winning the medium war.
- Companies don't have to buy all new equipement to make them
- They are cheaper than Blu-ray
- They can hold just as much
-  Cheaper players
I believe this is why Sony wanted a uniform medium in the first place. They knew if it came to the two types clashing they would have a hard time winning. As for the 800GB disk using nano-technology. You would most deffinetly need a new player because the way they read it is so precise you couldn't just update the firmware to tell the laser how to read it, you would need a specialized player and the room for error needs to be reduced so it can't vibrate and such. I don't know if that will also pertain to blu-ray and HD-dvd but I'm certain it will with any high storage devices such as a 800gig DVD. It shall be interesting to see if the public adopts blu-ray and HD-dvd now or waits a few years for nano-technology to produce far superior product that can be mass produced.

Someone stated earlier that games couldn't take advantage of a later switch to HD-DVD. But what if M$ would allow games to be stored on the HD as well as on the backward-compatible DVD layer? They could even use the same binary or a minor recompile with --HD, just display cutscenes (or other video content) in HD-DVD instead of DVD.

NO JOKE, I've read that a lot of hollywood is waiting to see which format the porn industry supports seeing as they release more movies than anyone else and has the clout to sway the industry one way or another.  

As for the "speed comparison" saying DVDs have a transfer rate of 11.08MB/s is completely bogus.

That is the transfer rate PER SPEED.

so a SINGLE SPEED DVD drive has a transfer rate of 11.08MB/s
meaning that the 4x dvd drive in the current gen Xbox is around 44MB/s!!!! Wow that's already faster than the first gen HD-DVD discs... Not to mention that due to the fragility of the BRD Sony hasn't yet been able to achieve 1X speeds.

The only reason the "transfer rate" per speed is different is because it's directly related to the disc's data resolution. 1X means the disc is spinning at 500RPM at its fastest (this is on the inside of the disc, the outside spins at about 350RPM for 1x) so if the disc holds 1.32MB of data in a single pass on the inside you'll end up with an "estimated transfer rate" of 11.08MB/s per speed.

So IF the BRD could spin at 500RPM they would be able to collect at a rate of 54MB/s unfortunately they can't get them to spin that fast... not to mention if they try to increase the speed they'll begin to run into bandwidth limitations with the actual hardware. Considering HD-DVD is physically constructed in a similar way to current DVDs... they'll have far less problems getting 2X 4X etc. drives out

For comparison the 360 will have a 12x DVD drive meaning the transfer speed will be 133MB/s... compare that to the 1X BRD @ 54MB/s that will be included with the PS3 and ask yourself which format has the better/more reliable data rates.

As for storage space saying the HD-DVD has a max capacity of 30GB is not longer true... Toshiba found a way to use multi-layer (read: three or more layer) storage meaning that they can increase the capacity to the same levels that the BRDs are achieving with their multi-layer versions... So the two new formats are on level playing fields in that respect... go back and consider the other advantages/disadvantages.

---not trying to attack anyone just clearing up a lot of misnomers about the number people keep throwing around.

Blu Ray isnt even a disk, its like a zip drive. 

And below is all I have to say to that ^

1.10    Will Blu-ray discs require a cartridge?

No, the development of new cost-effective hard-coating technologies has made the cartridge obsolete. Blu-ray will instead rely on hard-coating for protection, which when applied will make the discs even more resistant to scratches and fingerprints than todays DVDs, while still preserving the same look and feel. The adoption of hard-coating will also allow manufacturers to downsize players/drives and lower their overall media production costs.

Yes it has been done. It is just a hard version of those D-Skin things. HD-DVD supposedly is going to use it also. It is all because of the fact that one little scratch would kill data that compressed.

Why sony had blu ray discs in cases like dvd-ram discs at e3 during the ps3 unveiling?

deftonesmx17: HD-DVD uses .6mm protective layer BRD uses the .1mm http://en.wikipedia.org/wiki/HD-DVD

FYI. If the inside is spinning at 500RPM, the outside will be spinning at 500RPM as well.
