The Sanyo PLV-Z3000 LCD Front Projector refresh rate for 1080p/24 has been changed to 4:4 pulldown 96HZ
The Sanyo projector will still remain on the list since it is my understanding that the projector will do 4:4 pulldown 96HZ when smooth motion is turned off and when a 1080p/24 signal is received.
Originally the Sanyo PLV-Z3000 was placed on the list since the press release mentioned the 5:5 pulldown feature with 24fps sources and the specs mentioned 1080p/24 input feature. Click the following link for more information on why this projector was placed on the list

On pages 40-42 of the Home Theater magazine is a review on the Sanyo PLV-Z3000 Front Projector. The 5:5 pulldown feature on this projector does not work with 1080p/24 sources. In order to use the 5:5 pulldown feature you have to be watching a film based source that contains 3:2 pulldown and then the Sanyo projector if it detects 3:2 pulldown will attempt to do a reverse 3:2 pulldown. When the Sanyo projector is able to detect 3:2 pulldown and convert the signal to 24fps then it will do a 5:5 pulldown at 120HZ. The disappointing thing is that the Sanyo projector will not allow one to use 1080p/24 signals from BLU-RAY players with the 5:5 pulldown feature. The purpose of having 1080p/24 input capable display is to bypass the 3:2 pulldown process completely. This is the first time that a display with 5:5 pulldown was designed to not work with 1080p/24 sources. I am surprised Sanyo did not offer this important feature.
When smooth motion is turned on and a 1080p/24 signal is received, the Sanyo processing will first repeat the frames to 48HZ and then use interpolation of new frames to reach 96HZ with the negative effect of making film-based sources look like video.
How to get 4:4 pulldown 1080p/24 to work: It is my understanding from the review that if one turns off the Smooth motion feature there will be no interpolation of new frames on the Sanyo PLV-Z3000 and the Sanyo will do a true 4:4 pulldown 96HZ when a 1080p/24 signal is received.
Quotes from page 40 and 41 of the June 2009 Home Theater magazine review
"Sanyo's Smooth Motion is similar to 120-hertz feature that many HDTVs offer, but it's also different. When it's on, with a 24-frame-per-second (fps) input, the projector displays two repeated frames interleaved with two interpolated frames for a 96-fps (or Hz) frame rate. With a 60-fps source display rate, it interpolates one added frame to each real frame for a 120-fps display rate. With Smooth Motion off, there is no interpolation, and the display simply repeats the additional frames."
"The PLV-Z3000 also includes a 5:5 pulldown feature, but it doesn't operate as you might expect. It does not function with a 1080p/24 source; it only works with sources that have 3:2 pulldown."
"You can't use 5:5 pulldown and Smooth Motion together. If you select both, 5:5 takes precedence."
"Smooth Motion reduced motion lag a little, and as is typical of motion interpolation, it made film based sources look like video."
