The 4805 scales down larger resolutions. It looks great when it's scaling down HD because it just takes 1 out of every 3 pixles out from a 720p signal and that changes it to 480p. I think that's called 3:2 pulldown, but I could be wrong.
Yep, you are very wrong...3:2 pulldown has nothing to do with scaling is the process of making 24 film frames fit into 30 fps...here is a link: http://www.dvdfile.com/news/special_report/production_a_z/3_2_pulldown.htm
SDE is a problem for LCDs... you'd have to be very close to a DLP image to notice it. Rainbows are the problem with DLP projectors.
SDE is a problem of both technologies...normally it will be more visible in a LCD compared to a DLP with the same res but in the case of a Panasonic ae500 or Sanyo Z3 the screendoor will be more visible in the 4805...that to say sitting distance for the 4805 should be between 1.60-2.00 (most recommended but I like 1.75) x screen width. With the aformentioned LCDs you can probably sit 1.5 x width. Still, I too have the 4805 and it is awesome...the incredible contrast, color and detail surpasses even more expensive PJs. It even comes precalibrated at 6500K and here is for real not some bogus claims like other displays. And ISF calibration costs $300 so having it come calibrated from factory is superb.

Yeah, I really wasn't sure on the 3:2 pulldown for the name, so I'm glad you told me what it really was. It's been a while since I looked at specifics behind projectors. I don't want to get upgradeitis from learning about a lot of great stuff that's coming out
Even when I was sitting at about 1.5 screen width with my 4805 I really didn't notice SDE. Now I'm at about 2.0 screen width with my different room.
Maybe I need a new prescription for my glasses, but I need to be closer than 1.5 screen width for the SDE to be noticable for me.
