blu-ray to use mpeg2?

So they have decided to waste the extra space by using a crappy codec? Let me guess, when blu-ray discs become too small, they'll either start using MPEG4 or waste millions developing a higher capacity disc...

7 Things I love about Blu-Ray:
1) More expensive media
2) Old outdated MPG2 codecs... oh well there goes the much better "h.264 codec" that can
compress Hi-def videos at the same bit-rate as MPG2
3) Can only be made by Sony exclusively (like UMD's)
4) Draconian copy-protection DRM
5) Expensive Blu-Ray players that call home to disable/destroy your Blu-Ray player if
you have tampered with it in any way
6) Each Blu-Ray disc will be "LOCKED" to the "FIRST" Blu-Ray device that plays it... there
goes renting movies and games!
7) Root Kits
With all this, how can Blu-Ray fail? Its a win-win!

i'm in full support of HD-DVD now. That whole sony rootkit fiasco just put me over the edge. Unfortunately, w/ the PS3 that will undoubtly be very popular.. and the backing so split.. blu-ray has a good chance 🙁
You guys shouldn't be freaking out so much.
The only real advantage of the newer, sexier codecs (read: h.264) is the bitrate.
High bitrate MPEG-2 looks just fine, & isn't nearly as CPU dependant for decode (or encode for that matter) as h.264. How many of you have tried playing 1080i/1080p h.264 on your PC? How many of you have tried ENCODING high resolution h.264?
There always has to be a balance between processing power and storage/bandwidth requirements. If there is plenty of storage space and bandwidth (speed it can be read in this case) then MPEG-2 will work just fine.

MPEG2???
I can see them not using H264 because of all the cpu power that uses, but there are plenty of other good codecs they can use, such as divx or xvid, which shouldn't use a significant amount of cpu power by todays standards. If they start out with mpeg2 it will be hard to switch codecs later, because all the old players will need firmware updates.

Hopefully blu-ray will end up being the answer for extremely high quality video in say 1920 x 1080 or better. More likely it will initially allow for more extras and the ability to have several movies or close to an entire TV season shows on one disc. Being able to watch extremely high quality video in your hame may be a ways off though unless you can afford something like a Sony Qualia projector or TV. The Sony Qualia 70" LCOS KDS-70CQ006 rear projection TV (1920 x 1080) sells for ~ $11,000. Of course prices are coming down so maybe they'll be affordable in a few years. But by then there will be even better resolution probably.
Except that BluRay drives won't come close to being cheap for a long while, and the media itself will still be (probably) more expensive than HD-DVD media, based on preliminary (and not necessarily conclusive) information.
By the time the players start gettign down in price, technology will have come on and the processing power required by each may still be very different, but the technology used toi power the players will be cheap so it won't matter. It's like saying nowadays that maybe (just making up an example) a CD needs a 133MHz Pentium type speed chip to decode, while a DVD-A needs a 200MHz type chip to decode. It's not really gonna make a difference. Plus I think HD-DVD uses easier to make lasers or something, which reduces cost for them in that part.

if blu-ray becomes the dominant format, i will stop purchasing movies
AVC is where it's at right now. It will allow much higher bandwidth while using the same space as MPEG2. It's such a waste to use MPEG2 for next gen systems. There is a LOT more to this debate (I've been encoding and producing videos/DVD's for the past 5 years) but thats for a more technical forum (than OT)

Because Sony invented it?
mpeg2 probably has lower licensing costs (which will keep movie costs down), it has lower hardware requirements (keeping player price down as well as livability... i sure as hell don't want a dustbuster fan in my living room while playing dvds), and for the average consumer that is a lot of the reason to pick a format.
