What are all the differences between HD DVD and Blu Ray? Huh?

PFC5

When did HD DVD and BD get drums in their players?

This quote alone is proof you have no idea what you're talking about in regards to VHS vs. Betamax specifications. ----- The luminance bandwidth of ED Betamax is 6.4 megahertz (not 10), and the Betamax-II bandwidth used for Hollywood movies is 3.0 megahertz (not 5). Source: Sony's own documentation. (Also: http://www.doom9.org/index.html?/cap...roduction.html )


Well good. But they are more than just "real world" the same. The engineering specs are also the same:
- luminance == ~ 240 lines
- chrominance == ~26 lines

"Betamax makes a better picture" is a myth. The facts don't support the myth.

"VHS holds more minutes" is the reason it won.
And I suspect (hope) Bluray wins for the same reason.

WTH are you arguing about this for? Being right is so important? This has nada to do with HD DVD/BD.. *yawner* VHS is all but gone, Betamax, gone eons ago.. let them rest in peace!

Frequency response is 9.3 Mhz actually, I said 10. I was wrong!
Video frequency response was a key advantage only obtainable though with metal tape that was used.

I never even mentioned luminance bandwidth. But thanks for the data!

And there is no need to be rude. Nobody is right 100% of the time, I suspect not even you.

If you want to nit-pick every little statement go for it, I could have a field day, but I have better things to do with my time.

Maybe this would be a good time to stop this "debate" about two formats that are gone alerady, because it does not really matter anymore.

Good advice!

In memory of all formats that have gone before us.....

If someone says 2+2 = 5 I am going to correct them. False information should not be allowed to exist without correction.

And it doesn't matter that it's old. The movie "300" was about a war that happened ~2500 years ago, and yet we still go back and revisit it, to see what lessons we can learn from those brave warriors.

And finally, the Betamax/VHS debate happened because it's relevant to today's HD-DVD/Bluray battle (see below).

My reasoning is based on Historical Fact:

VHS held more data (minutes of video), and therefore it won the war. VHS was a better value to the consumer, and it's reasonable to think history might repeat itself with the Bluray's ability to hold more video. That's my "holding water" argument.

Was it not more because it makes a cracking movie to watch and to try and rinse another big fat wad of cash from people going to watch the film?

There was another key factor for VHS over Betamax they you are forgetting, and that is that VHS was also the cheaper format for both media and players.

While capacity was a big factor, there is a slight difference this time, we now have hard drive recorders etc for recording off TV, and DVD recorder worth its salt also has a hard drive, meaning just to watch that last episode of TV show X no media is now used.

These things are never as black and white as people would like them to be. It's always several factors, not just 1 thing.

Also Betamax wasn't capable of recording full sporting events. Meaning if you taped the game, you'd only get half of it. Something neither HD DVD nor Blu Ray will ever have a problem with.

PFC5

But the VCRs back then were used MUCH more for recording/time shifting so capacity mattered more for that than prerecorded movies. That is the disconnect from then and now.

Sure these HD formats can be used to store data on PCs, but that is a different store from HOW people use DVDs now. They ARE for just watching movies and the only real world place where the capacity matters is on computers.

I have stated that if follywood had a brain they would want HD DVD for movies and BD for computers. That would just make it that much harder to pirate movies with them on different formats. Why didn't they think of this?

It probably is to him as I kicked his a$$ to the curb 2X already this week, so he wants to be right with someone.

daleb

That's the drums I heard!

That link you posted with the BD stats listed a vast majority of BD releases using MPEG2. If they don't release MPEG2 anymore, than this must be a recent change. Still, a necessary one.
