I've never messed with color space much, but I am curious on instances when you would want a full range vs the limited range for an HTPC. I have an HTPC, use 7MC and TMT/PowerDVD exclusively. I connect via HDMI through an AVR passed through to my plasma tv (1366x768). I have an nvidia 9300.
I can change the range of my TV through the service menu to from 235 to 255. I can change color space and settings (RGB or YCbCr). So for playback through 7MC and color calibration, what is the best practice regarding these settings?
