This part isn't absolutely necessary but it's nice. Otherwise,
you can still compensate by adjusting the saturation (color)
on your TV. It's the other stuff that makes the big difference.

It's in "10. Configuring mythfrontend." under Playback:
The "adjust" filter was added after 0.14 and I haven't updated
the docs yet. However, my message was self contained. The "mysql"
statement will add the adjust filter and parameters for recording
and the "kerneldeint" can be added for playback on TV Settings->
Playback in the Custom Filters text box.
update channel set contrast=23400,brightness=34000,colour=32000,hue=32768;
update channel set videofilters='adjust=18:237:1.0:35:220:1.0';
