As for fill factor, the Cygnus IMX-931 does a fairly decent job of increasing percieved fill factor, (you can see their website). I have one with my VW10HT and it does a fairly good job. Better blacks and scaling would be a good improvement...I currently am using a DVDO in the Y-Pb-Pr out mode and it does improve the quality of the picture, though it doesn't come close on small details to the smoothness of my CRT projector, (ie the opening scene in Gladiator where the troops are marching (arrows flying, etc.), the individual soldiers seem quite a bit more pixallated on the VW10HT than the CRT.
