Dear Attila:
This was my original bugreport - is it o.k.?

Hi:
I continue to get a segment fault in mplayer when trying to use
-vo [x]mga.
I've just found and subscribed to this list, and I would like to
thank you for the work you're doing.
The fault occurs in both linux 2.4 and 2.6, across several upgrades.
I'm also having trouble with -vo xv and -vo sdl, both of which
show the left half of the frame fine, while the right half is
marred by (hazy) vertical black lines. -vo x11 works fine.
Below are some of my results. Thanks again,
/frank
