Comment 1 for bug 615235

The bug was observed on a friends system that suffered the "inadvertent contrast-set-to-zero" problem. I can reproduce it on my system. Start totem on any video, click edit->preferences->display .Slide the contrast to zero or very low, close totem, and start mplayer on the same video.

mplayer -vo x11 <filename> will display correctly, while mplayer -vo xv <filename> does not.
