Can someone enlighten me on these types of video capabilities? I'm aware of the frequency differences for vertical and horizontal resolution, however I see many publications refering to the 1080/24p as being the "best picture" possible. I realize that many brands and types of sets resolve a variety of vert/horz frequencies, however I would believe that 1080/60p would be the higher or "better picture" possible if your TV is compatible/capable. So why the push for 1080/24p or am I misunderstanding?? Also......Is anyone aware of other firmware upgrades for the BDP-S1, specifically DD Plus/DTS HD bitstream via HDMI or any other means? Thanks.

1080p24 is what's recorded on the disc (for films). Getting this native rate signal out of the player, for displays that are capable of accepting it, is the best way to do it. The display can then refresh at 48Hz or 72Hz and give you the best progressive picture possible from your player/display combination. Unfortunately, there are two current problems with 1080p24: there are few displays at this time which accept this rate and some of the ones that do will change the rate back to 60Hz because that's the native rate of the display. Neither problem is a reason to exclude this output as an option, because more displays in the future will accept 24p and a higher percentage of those displays will properly refresh at a multiple of 24 (48, 72, etc).And what about 60p? The encoding on the disc is obviously not 60p. To create this rate, the player will actually output each successive original frame either 3x or 2x in order to get the rate from 24 to 60 (Frame 1 = 3x, Frame 2 = 2x, Frame 3 = 3x, Frame 4 = 2x, etc giving the appearance of 60 frames instead of 24). As you can see, Frame 1 appears for 3/60 sec, Frame 2 appears for 2/60 sec, Frame 3 appears for 3/60 sec, Frame 4 appears for 2/60 sec, etc and this can introduce an artifact called "judder" (a "jerkiness" in the on-screen motion caused by each successive original frame appearing for a different length of time). Some people are sensitive to this artifact, some people will only notice it if it's pointed out to them and others don't notice it at all. Outputting a 24p signal and letting the display refresh it at a multiple of 24 (48, 72, etc) eliminates this problem.

Many thanks. Just the information I was searching for. What a great reference site. Just like owning any hi-end equipment your senses become accustomed to it and you begin seeing (or hearing) differently (you grow). Your visual and auditory palattes (for lack of a better term) become educated and so the quest for more; a "better" picture and/or sound quality experience continues. That's the audio/video enthusiasts plight, right? After viewing my Sony 60" XBR2 LCoS display for a while now, while very impressive and a great TV, I'm now seeing subtle artifacting with various sources, most obvious is some smearing with camera movement such as when playing the blu-ray disc "Night at the Museum" which looked stellar on the 63" Samsung Plasma @ BB, while it looked great on my set-up it wasn't the same experience. It wasn't as 3 dimensional and the Sammy had a more pleasing color pallette than on my set as it should for a $4k difference right? I think I'm ready for a professional calibration or at least for now use my Video Essentials to dial it in. Thanks again!
Picture on this display was fantastic.
I'm sure it a beautiful display...I've not viewed one yet...thanks for the tip...
Most films are made at 24 frame/second. High def discs of both formats store most movies at 1080/24p. Since 60 isn't a multiple of 24, converting 24-> 60 causes motion distortions(Judder). It would be preferable if your TV accepted signals of 24 fps or multiples of 24, and played them back as such. Right now, few TVs accept 1080/24p.
That's a gross over simplification, and I'm sure others can give better details.
BTW, the full resolution of HD is 1920 X 1080.
