[mythtv-users] black border issue Knoppmyth and EPIA(HushPC)-can't get rid of it...

Found the answer by looking through:

http://www.kingcot.eclipse.co.uk/unichrome/xorg.conf.txt

I needed:

        Option      "TVVScan" "over"

Did the trick.

Now, does anyone have any suggestions to make the picture a bit 'crisper'? 
The picture looks great, though ever so subtly out of focus. I wouldn't even 
notice if I didn't compare it side-by-side with my PVR-350.....

later,

Paul
