WOW! You two posters need to do your homework!
The Persistent Storage in the HD-DVD players is ~ 151 MB!
Most of the HD-DVD discs do have all of the main Trailers and subtitles on the disc with in 15 or 30 GB!
The Internet downloaded options allows a movie studio to be able to provide the subtitles in ANY language they can create! (50 GB) would be nice but it can not be dynamically UPDATED or AUGMENTED! Same with the Movie Trailers! This allows the studios and the Film Makers to be creative. And from a marketing perspective, allow the studios to add extensibility to films you may already have in your library, so that you now WANT to buy them again, in the new format!
Toshiba and the
DVD Forum (the STANDARDS body for all things DVD related, which BTW, does NOT include Blu-Ray) are not stupid nor do they think that you are either! Of course you can not watch your
BD or
HD-DVD Movies on a SD DVD player!
M$ makes the decisions for the X-BOX 360 not Toshiba, so I suggest that take that issue up with them! I'm sure they have some good reasons, just as Sony did when they delayed the PS3 to get the Blu-Ray drives included into that platform. (Maybe not such a great move in hindsight, eh Nintendo?)
Disney while being a self proclaimed entertainment powerhouse, does not solely drive the Movie industry. Sony's own philosophies are somewhat hypocritical, in the sense that they Stated that they did not want to produce on an HD format that was endorsed by the porn industry.... this smacks of Moral High Ground to me or just plain BS.

Did this apply to DVD, what about DIVX? When in-fact, Disney owns Touchstone Pictures, which has produced some very border line films, if you ask me!

Also, exactly why is it that EVERYONE else in the Movie industry can MASS produce their movies that retail at $19.99 or less but Disney movies tend to be $24.99 and up? If you wish to follow Disney, wherever they go, so be it. I would advise you to just make sure you go to the back of the church or school house first, so you can catch them sneaking out of the back to pick up some naughty stuff, on their way straight to the BANK (with our money)!
I would suggest that you investiGATE before you HATE!

THAT is what it is truly all about!
Yes it is only an 8 step plan! Luckily, Blu-Ray Addiction is not as bad as REAL drugs! Right Disney?
