This has been hashed to death....why do we need another thread on the topic? The next time this topic should appear is when the BD players are out and we can compare actual working consumer units in head to head comparisons.....right now it's the same "spec" comparisons that have gone on since we knew there would be a format war.
kindly link me to a thread that has facts in 1 place. I am just trying to understand why consumers think that BD is going to be so much better than HD DVD .
Here are two threads to get you started:



When I googled...many more came up. There are a couple of master threads here too. I'll admit you've got to wade through all the other threads to recapture the basics....but it's really has been discussed and compared as much as it could be. I picked the two threads from dvdtalk, cause they were handy and they will give you the "spec" comparison. Cause really right now that is all we have until the face offs take place once BD is in the consumer's hands.

Sorry to come off as harsh, but we get a ton of redundant threads asking the same questions.....if I see another thread wanting to compare the difference in features between the two toshiba players ;)

Good Luck

No problem. I just wanted something to compare side by side even if 1 side doesn't have a working player. And I have been reading thru all the ridiculous rant threads which prompted me to wanting a side by side comparison.

Good threads and exactly what i was looking for.
The current state of the Blu-Ray sound sad to say the least, if this information is true.

From the Blu-Ray forum:
Sony is going to give us an LPCM 5.1 track (because the players can't support the more advanced audio codecs) then realize the the LPCM tracks are only 48/16 - ie. CD quality only - because they can't afford the space for 96/24, because they are needing a higher bit rate for Mpeg2 because its not as good.
I read that BD has more storage space than HD-DVD, but I guess that is false. It looks like BD will initially be a 25GB single layer disk for new releases where HD-DVD is 30GB dual-layer disk. So currently HD-DVD is the storage leader too!

This information about BD adds more CONS than PROS.

So the initial release of BD will be a very high bit rate MPEG2 with CD quality audio tracks!? That's SAD!! :eek:

HD-DVD is light years ahead of BD as HD-DVD is currently supporting stunning 1080i MPEG4 HD video with HD quality audio tracks.

Now I understand why BD need 50GB disks, it just to keep-up with HD-DVDs. :rolleyes:

The HD-DVD specs sure more detailed than Blu-Ray Specs; I guess Blu-Ray is still in flux. :D

Clearly, HD DVD has the backing and experience of the entire DVD Forum to help it to formulate and decide its specifications right to the dot.

Blu-ray has to decide on everything from ground up and it certainly does not look as good as the technical specs it claims to have. Thus, everything is kept simple for BDA, so long as the consumer "buys into BD advertising campaign".
