[MPlayer-users] only green screen on TV-in attempt

[Timo Reimann]

Does really *nobody* has a clue concerning how to get
a TV picture on my screen instead of green wall of
nothing? This is driving me nuts!

Somebody told me it could be an overlay issue, I tried
'nooverlay' and 'overlay' but it didn't help. :(
