[mythtv-users] Screen corruption with fglrx X driver

[David Gee]

Thanks to all for the various suggestions; using the --geometry argument
fixes the problem with the screen garbling - I'll havea a fiddle with some
of the xorg.conf settings and see if I can fix it for fullscreen too using
the ideas that have been put forward.

When viewing widescreen HD content, I also saw the duplicate videos stacked
on top of each other. How do you change which deinterlacer is being used?

Regards
David
