[mythtv-users] Video display settings

[David C. Dean]

To All,

I've found the documentation on how to change the brightness / contrast 
/ etc. during TV playback, but can anyone point me towards instructions 
on how to make those changes global to ALL channels so I don't have to 
tweak them all manually?  I saw somewhere that its just a sql query, but 
I dont want to tinker without knowing what I'm doing.

Thanks!

Dave
