well..I output PC range off ffdshow and my displays all have PC range(so no levels conversion needed)

that's my RGB32HQ picture :

now w/ ddcc doing the gamut conversion(8bit LUT created in ddcc) in HR :

and that's w/ a 16bit LUT from yesgrey's app in t3dlut() :

so that 16bit LUT is way too dark, and my .ini settings appear to be OK...even yesgrey agrees.

and I'm getting opposite results when I put this LUT in madVR

that's w/ ddcc(8bit LUT created in ddcc) in HR :

this is the stock HD LUT in madVR :

and this is my custom 16bit LUT :

I know ddcc "works" coz it matches what the PS script outputs(slightly better of course)...

I think you may wanna give the option to the user to choose untouched levels or TV>PC conversion, and then make 2 LUT's :
SD: REC.601 (untouched levels OR levels expansion from TV to PC)
HD: REC.709 (untouched levels OR levels expansion from TV to PC)

but anyway, the CMS is pretty broken right now I think, waiting for yesgrey's feedback
