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.
