[mythtv-users] Video sync not working in TV out

[Owen B. Mehegan]

Aha, I fixed my own problem...

Changing Option "NoDDC" "1"
to...
Option "ModeValidation" "NoEdidModes"

...stops the annoying sync problem. But now my display image has a  
black border around all four sides. Didn't have THAT problem before  
this upgrade either. I guess I need to keep tweaking my X settings.  
Maybe change some of the mode parameters? I'm open to suggestions.
