A suggestion and a solution:
To see if its Myth thats adding the black space (as opposed to
the broadcaster) go to the Frontend Utilities/Setup, Setup,
TV Settings, Playback, General Playback (2/8) and change
Letterbox Color from Black to Gray (if you already haven't.)
To get rid of the flickering (VBI), on the same page as above,
try a value of 2 in the Vertical Scaling setting. That worked
for me.
When Greatly Enhanced Playback Groups gets implemented, you can
set the Vertical Scaling on a group bases rather than for all
shows (Trac 8088.)
Good luck,
Bill Meek
