Blu-ray vs. hd-dvd

Blue ray will have more storage space but is harder to make and costs $$$

HD-DVD has less space but the players can be backward compatible and the media is much easier to make/cheaper
 
space is most important. special features, high bitrate vid, all need to fit on one or as few disks as possible.
 
isn't bluray something like DVD-ROM and HD-DVD a "codec"? Bluray doesn't necessarily have to be DVD, right?

Blu-ray is disc-based, but [right now] it definitely isn't compatible with contemporary DVDs.

HD-DVD will still use a red laser, but will use a new codec to store information - H.264 is one of the leading ones.

Ah sorry, I meant, that Blueray is something like a CD-ROM, DVD-ROM, Floppy drive, just a "drive" but HD-DVD is a codec like SVCD, etc.
 
HD-DVD = 15 gigs one layer or 30 gigs two layer price: $200+ $10 per disc

BluRay = 25 gigs one layer or 50 gigs two layer price: $600+ $40 per disc
 
Ahhhh so much misinformation:

HD-DVD
HD-DVD is the recently approved specification submitted by NEC, Toshiba, and a host of other companies - formally known as Advanced Optical Disc. It uses a blue laser for its lens and will store roughly 15GB per layer.

The ROM spec has recently been approved by the DVD forum - hence the name change from AOD to HD-DVD. The video codec for the read only media (movies) is still technically undecided. The front runner, as far as I remember, is VC9 - which is the video codec used for Windows Media 9, minus the digital rights management crap.

The audio specs for the ROM is still completely up in the air. Versions of Dolby Digital and DTS are highly likely for lossy audio with a new codec like MLP for lossless compression.

HD-DVD players will read current DVD discs, but an old-school DVD player will not read a HD-DVD disc.

Players and media should hit the market sometime in 2005, probably depending on the competition from the Blu-Ray camp.

Blu-Ray
Blu-Ray is the specification put forth by the Blu-Ray Disc Foundation, which includes Sony, Dell, HP, Matsushita/Panasonic, TDK, and other big name electronics companies. Their spec was never submitted to the DVD Forum for approval so the AOD team pretty much won by default. Blu-Ray also uses a blue laser for its lense and optical system and will store rougly 25-30GB per layer.

I'm not sure of the specifications have been completely set in stone. The current spec for read only media is MPEG2 for video like current DVDs and television broadcast and updated DD and DTS codecs for audio. Recent comments from Sony seem to imply that they are rethinking their video codec to possibly include support for VC9 or MPEG4-AVC (also known as H.264). Not sure about lossless audio codec support.

As far as availability, a Sony Blu-Ray recorder has been on sale in Japan since last summer for about 3000 USD. A new model from Matsushita/Panasonic (I think it was Panasonic) was recently announced and should also go on sale in Japan late summer/early fall. A Blu-Ray player (without recorder support) and movies will available late 2005 with massive support from Columbia/Tristar.

Blu-Ray players will read current DVD discs, but an old-school DVD player will not read a Blu-Ray disc. The Blu-Ray group recently announced an optical system that will read both red and blue laser media.

WTF neither of the standards have gone into production. Did you pull those numbers completely from your rear orifice?

not 40 per disc. they said initial manufacture might cost a little more as with all new media, but not anywhere near that.

Thate article is from January of 2003 and is rather outdated. HD-DVD9 is a dead standard as far as I can tell, thank God. The DVD forum recently approved AOD as the next generation movie media and it will most certainly be blue laser based.

The Blu-Ray group has every intention of competing against the DVD forum this next generation. I fully expect a huge format war in the next couple years. I wouldn't pick sides just yet, cuz this is gonna get bloody.😉

Unless you have a larger TV that supports HDTV resolutions, I doubt you'll benefit much from either.

Me, I'm waiting quite anxiously for whoever wins. I'm not buying into D-Theatre, so I'll just wait for Blu-Ray or HD-DVD.

hdtv already does that😉 dvd players are cheap. u can still buy vcrs. dvd format isn't going away totally for a long time thanks to pc usage, so its never going to be like vcr. but to hold back tech for compatibility..that would suck. dvd-9 already is lousy, it can't even hold entire movies like schindlers list. that came on what? 3 discs? 2 for movie one for bonus? i don't like that. i want as much on one disc as possible. expect more not less.
