Thanks for the response, it turns out the STB was set to give a 720p feed. I just switched it over to 1080i. However it seems as though the blacks/colors aren't as vibrant as when the source is my Xbox or USB drive with HD content. Is this normal or should I be expecting PQ on par, or close to that of any other HD content? I guess I could say the PQ looks flat, with kind of a light gray haze?
My current settings are:
Cell Light 10
Put gamma at -1 and put film mode to "auto 1." Auto 1 is the only mode that deinterlaces properly. Turn everything else "off"
Use Warm2 white balance adjusted as follows:
Custom Color Space (1st # is red, 2nd is green, 3rd is blue):
Blue: 5, 0, 39
Yellow: 47, 50, 19
Cyan: 36, 48, 48
Magenta: 40, 0, 42
as per page 163.
