I have zoom pro v6 on a core duo PC within widescreen 1680 x 1050 resolution and radeon HD3650 graphics., so lots of available cpu & graphics power.

is there any mileage in tweaking zoom's filter settings for any of : avi ( divx), avi/mkv ( H264 ) , wmv, or native dvd formats in order to improve upscaling to this resolution - or is everything fully optimised already on the player's default settings ?

(I did find an old guide for adjusting ffdshow within zoom 5 elsewhere, but did not see any difference when I followed its advice.)

is it possible to achive results like those from windvd9's upscaling ( which actually only affects DVD & is greyed out for AVI)
