1) I detect no differences in comparing film based segments when running 24p or 60p from my Anthem D2. Pans (slow or fast), moving images, etc. all appear to be the same... of course this is not a direct A/B comparison as it takes a while for the hdmi handshake to finish when switching output formats on the D2. Perhaps the negative effects of "judder" are overrated.
2) Wouldn't the colorwheel have to change speed? Should this not be subtly detectable when switching input from 60p to 24p and vice-versa (audibly I mean... I certainly hear my colorwheel spin up and down when the projector is turned on/off... it is also subtly detectable when running if I put my ear close enough)? I can detect no changes sonically (projector is the only noise producer in the room when system is muted)... perhaps the fan noise overwhelms this speed change.
No big deal... plays fine either way I just haven't been able to detect a single advantage feeding 24p vs. 60p for film based materials.
It could be that your Anthem D2 does such a fine job of video processing in the first instance!
My HDMI feeds pass through the AXC-A1XVA (5805ci) and the differences are subtle. I have also found that there is a variation of effect between different discs.
Does the menu of your PJ confirm that it is actually receiving 24hz while the disc is playing? The Sharp requires players to be in "forced" 24p output mode because the upgrade does not change the the 60hz only capability message it sends to connected equipment. Officially, Sharp have advised their technicians to do the upgrade when customers notice a certain "flash' with 24p material.
One change that anyone should be able to notice is the the scrolling credits at the end of a movie. 24p should be smooth without judder, 60hz there will be a slight judder as the credits scroll. I have noticed that the film material presentation is smoother overall particularly when the camera is panning. I am particularly sensitive to this for some reason and previously found some panning shots very difficult to watch.I am also accustomed to PAL DVD material (50 hz) which does not require 3:2 pulldown and has smooth scrolls and pans.
Like you, I have also suspected that some of the improvements of the firmware upgrade were brought about by tweaks other than for 24p, but that has not been confirmed by Sharp. For example where I would previously notice some video noise on certain discs, this has disappeared. I also feel that the picture is a bit sharper overall, but this is a very subjective observation.
I have now set my blu-ray players to forced 24p output all the time and I only wish I could do the same for the Onkyo HD-805 HD-DVD player!
