Hi mate.
One of the ways to help get rid of that dot crawl....
The Strata models all have 3 preset picture modes which you can use to find the right balance depending on what you are watching. When one of these picture modes is changed a new picture mode is made called M.
Firstly flick through the preset modes until you get to picture mode 3. Now this mode as default is very dull and soft but if you bring the contrast level up to about 50ish and the brightness up to about 50ish, increase the shapness level and disable all the picture tweaks (DNR, black stetch) then things should start to look and move better with less trails.
The last thing to do is ALWAYS have the tv set to "progress" mode in the menu as this will give the very least artifacting.
My settings:
CONTRAST - 55
BRIGHTNESS - 50
COLOUR - 48
TINT - 0
SHARPNESS - +15 (some like it less but on my set it seems just right)
SCANMODE - PROGRESS
DNR - OFF
BLACK STRETCH - OFF
The matter of geometry on these sets is a living hell to try and get right but give us a shout if ya need any help
