For some reason blackbox won't accept that command in
/usr/X11R6/bin/startblackbox.  It just kicks you backout as soon as you
login.  So for now I'm trying:
Option "blank time" "0"
in XF86Config-4 in the ServerFlags section.  Not sure if that will work or
not.  I just put it in there.

Sorry that was just a typo in the email.  I do have TVOverscan in there.  I
tried different settings from 0.1 up to 1.0 and the only difference I see is
the number of flickering lines on the blackbox gui right before mythfrontend
starts.  The black bands on the top and the bottom of the screen don't
change.  They are pretty large too.  I'd say at least an inch.  My pvr-350's
tv out doesn't do that.

XvMC?  Not sure what that is exactly.  My OSD while watching TV is in color.
If I pause I get blue background with a red boarder and white writing.  I do
not have the deinterlace filter turned on.  I tried turning it on but that
looked worse so I turned it back off.  That's only for monitors right?

I've seen lots and lots of modeline examples posted to the list but I really
don't understand what they are.  I tried just pasting in a few but not
knowing what I'm looking for I'm just blindly picking them.  I couldn't see
any changes with the few I tried.
