Hauppauge HD PVR Green Tint

I was having problems with all my HDPVR recorded video having a green tint. It turns out that the values for "hue" in don't map to the values used in the latest HDPVR drivers.

For example, the HDPVR's default setting for hue, as determined by the ArcSoft Total Media Extreme application, is 0. But if you set the "hue" value in to 0 you get green tinted recordings. Fortunately, if you open up TME and examine what it thinks the HDPVR settings are you'll see that the hue/tint is now at -30.

It looks like the value for hue range from 0 to 255, while the HDPVR driver values range from -30 to +31. Setting the value to 128 makes the HDPVR have neutral tint (i.e., a TME-displayed value of 0).

Interestingly, there doesn't seem to be a similar problem for the other values such as contrast. A value of 64 for contrast shows up as 64 (the default) in TME. Go figure .
