The author got almost everything right except for this:

Now, an important side note is warranted. We are talking about the common form of 1080p in the NTSC world, which is 1080p/60. But another way to output the information is to simply transfer the data on the disc in its native 1080p/24 format without doing any conversion to 1080i/60 or 1080p/60. Contrary to what you might expect, 1080p/24 transmission actually can have some incremental benefit over 1080p/60. However, in order to take advantage of 1080p/24 output on the players, we will also need projectors and TVs that can recognize 1080p/24 signals and convert them to 48 or 72 Hz. The vast majority of HD compatible TVs and projectors that have been installed and are being sold today do not have 1080p/24 capability. However, they are beginning to appear in anticipation that Blu-ray and HD-DVD players will be able to output that particular signal format.

The advantage to 1080p/24 transmission is that it can eliminate artifacts associated with the 2:3 pulldown conversion that is common in the NTSC 60 Hz world. The disadvantage is that it adds cost to both the HD disc players and the video display products. Moreover, the vast majority of consumers are not bothered by, or even conscious of the artifacts that it is intended to eliminate anyway. For the most part, 2:3 pulldown conversion is invisible to the viewer except in certain types of scenes, and even then they would not be noticed at a normal viewing distance on most 40" to 50" televisions.

Nevertheless, for videophiles using larger screen systems, 1080p/24 transmission and processing will eliminate 2:3 pulldown artifacts that they can certainly be aware of and bothered by. So as TVs and projectors come onto the market that are able to accept a 1080p/24 signal, both HD-DVD and Blu-ray players will show up that are able to deliver it. In fact, the next wave of higher priced Blu-ray players to hit the market this fall should have 1080p/24 output as an option. A good percentage of the higher end videophile market will be motivated by 1080p/24 transmission, so HD-DVD will need to follow suit in a timely fashion.


This pulldown problems exist even back in the vhs and dvd days, the difference between recording equipment and commercial sets have since been evident but till to day have not be eliminated. His advice to pay a premium for so called 1080/24 sets are beyond my comprehenssion. People dun see a need in achieving the extra 1% in image quality, so why bother. Pulldown is a very good compromise technique. Heck how many of us run movies with 72Hz refreshers on our progressive scan native comp? People either didnt knew or doesnt care. The latter for me.

This might be off topic, but I hope someone here can englighten me.

I know Dolby Digital 5.1 and DTS are too different audio format in DVD.

Almost all the original DVD that you can find in Speedy (either local released or imported ) or www.buy.com, all the new released titles only have DD 5.1 .
There are only few that special edition titles that have DTS.

And almost all the pirated DVD in malaysia that has both DD 5.1 and DTS.

My question is, who encodes the DTS into these pirated DVDs?
The original studio or the pirated industry?
if the formal one, why I can't find any original title that has DTS version?
if the latter, how they get the audio track that the original version not even exist? And is the DTS in these DVDs really a true DTS?

I know DD5.1 and DTS are not much different.
But it bugging me that my original DVDs only have DD5.1 and those pirated DVDs out there have both.

The pirate copies tat u get is Region 1 copies with full goodies, where as the Speedy ones are Region 3, minus all the goodies.

The DTS differs not much from DD5.1. Perhaps the most significant difference between them is the CENTER channel normalization practised by DD but no DTS. So when u have really soft dialogues movies, switching to DTS will help. The dynamic range also differs, but not much as impactful.

Those pasar malam's DVD's DTS tracks are fake one
Jack sparrow just re-encode it from the existing DD5.1 track, some even is from 2.0 track laugh.gif
So it's not the real DTS you're hearing, it's just re-encoded DD5.1 with higher volume.

Some ori DVDs has real DTS, especially those special edition or the so called DTS edition. 
Most of the hollywood studio's movie DVD are release in DD5.1 only, only a selected fews are encoded with DTS.  Even my LOTR:EE trilogy also are in DD5.1 only.  Anyway, DTS DVDs are easily found in playasia or yesasia

I haven't seen the price of BR movies yet, but so far what I seen is the price of HD-DVD movies are the same with normal DVD movies.  So it's still quite affordable.  Wonder when Georgie will release a HD version of Starwars: Complete Saga. biggrin.gif Woot!!

U were saying?

Just because u have a piece that doesnt have DTS, doesnt mean that it depicts the actual statistic. DTS have just as much demand as with DD. DTS do sound louder for a reason, not because it was purposely made that way by pirates but it's dynamic range is different.

Yeah, PS3 owners might not be running to the shops to buy Blu-Ray, but if there's millions of them out there before HD-DVD, movie studios will definitely be favoring the Blu-Ray platform. You can't ignore millions of potential buyers who already have the hardware ready.

Threadstarter: Sorry for being slightly, off topic, but it's not totally off topic.  Firstly, i don't believe in God and secondly, i hate cats. So, no love lost. Cheers.

Well, for the time being, BD leads.

some has suggested that Peter Jackson has power on the releases of his titles. And as he is now 'kawan baik" Bill gates .. you imagine lah ...  tongue.gif .. so it must has more to do with Jackson than New Line.

and as for the PCM versus TrueHD/DTS-HD MAster. All are lossless tracks. TrueHD/DTS-HD Master are the newer and more eficient codes. Some even argue that PCM is not a true 'lossless'. I am wondering why a 'new' format like BD would want to use ancient and less eficient codecs such as PCM and MPEG2. Everything about BD is new, more superior. So why apply something from the Melinda Gordon' store  laugh.gif .

one more thing .. Blu-ray drive has reached LOWYAT. Compuzone is selling the Panasonic BD bare drive at RM2999. .. and people are getting the PC supported HD DVD add on for RM730 from Japan! When the BD camp people manage to get the price down to RM1,000, the HD DVD drives would be selling at RM219. Another reason for MS to throw its support to HD DVD.

Wo Wo WOOOO. Is it really that expensive? Perhaps PS3 as a computer addon would be more feasible (if it's possible at all). Perhaps some genius should write a thing for a PS3 addon.

Your LOTR scenario is far from the common case. Optimize for the common case, that has been the rule which has driven the industry forward. When you overengineer, what you get is... the PS3. It's late, overpriced, and not really revolutionary after all (fanboys may beg to differ).

A single format would be good for everyone. No need to worry about whether their equipment will be able to read this or that, or buy two different setups just to play their movies. Reduces manufacturing costs since there will be more volume. There is nothing wrong with saying one is better than the other based on its merits, provided you have something to back it up with.

In this case, i think it's quite clear which format would be the best for the consumer, especially one without too deep a pocket. Not picking a side is like forgetting to zip your fly with nothing to show for it even.

IMHO, PS3 is a PS2 with bigger paper specs. The higher resolution adds little to gaming dimension. I mean there is not much to shout about, PC gamers have long been riding the megapixel gaming wave. So wat makes the PS3 so different? Beats me.
