OK, I received my new voltage convertor and did an average test of 3. I must say it does help to reduce the chroma noise. But since I capture in RGB the ,25,2 addition to the temperalsoften doesn't work and I don't want to convert to yuy2 or something like that, I want to keep it RGB.

Or I could just abandon the RGB stuff and capture in yuy2.

About the capture card settings, wouldn't it be best to just set them to the defaults and manually adjust brightness and saturation later using avisynth?
