[MPlayer-users] blank video playback with xv

[Doug]

With an ATI Radeon Mobility M7, mplayer 1.0pre7, and xorg 6.8.2 I'm
getting a blank screen (well, it's slightly blue due to a color key
value of 30 - various settings of color key confirm this - at least
this much is working, sigh).

Is there anything in this output of xvattr that would explain the
blank screen?

Found Xv 2.2
