[mythtv-users] xScanDisplacement

[Jeremy White]

Hi Joe,

I am using the kernel framebuffer drivers, and the
main Myth display (as well as the entire X desktop)
is nicely centered and fills the TV.

It's only when I switch to watching a program that I lose
a chunk off the right side of the screen.

Cheers,

Jeremy
