I have all my devices hooked into separate inputs on my tv so I can set 
contrast/brightness/color individually.
I calibrated my tv component & HDMI 2 using the DVE disc in my xbox 360, 
and then the HDMI3 (MythTV) input using mythdvd
I then connected my xbox 360 to the pvr-250 input via s-video and 
calibrated the recording settings for the PVR-250 (using the G key and 
liveTV mode)
I then copied the values to all the channels with a MYSQL command. I 
noticed the default contrast & brightness settings clipped the black & 
white quite a bit.

I found a filter for virtualdub called color tools that shows the video 
waveform, like a scope. That let me set brightness & contrast. This 
filter also had a vectorscope that let me set color and tint, but I 
could never get it to match quite right.
