[mythtv-users] Component TV Out Problems

There is no overscan setting for Component Out, only for S-Video,
unfortunately.  In Myth, you might be able to compensate for this by
setting the GUI size to smaller than your resolution in the setup
menu, then checking the box to play video at the same size as the GUI.
 The only other method I've come across is to find your television's
service manual (not the user manual they give you, but the one for tv
repairmen), and find a way into its hidden service menu and change the
overscan settings there.  Obviously there's a reason its hidden, and
there are ways in there to mess things up pretty well.

As far as the refresh rate, again, you're locked into the refresh rate
determined by the "TVStandard" line in your Xorg.conf.  If you have
flickering, its most likely because you're creating an interlaced
picture, 1080i.  The component out doesn't seem to quite 'sync up'
with any interlaced displays, so thin elements of a GUI will jump up
and down.  Using 720p eliminates this, but then you end up with a
slightly fuzzier picture if you have a native 1080i set.  Ideally I
think one would use 720p for any menus or Gnome, and switch to 1080i
only to display video.  This would be possible if not for a bug in the
Nvidia drivers which prevents properly switching between these on the
fly.  Can anyone confirm if this bug still exists in the new 100
series drivers?
