mplayer default(xv) video output error?

[lveax]

hi

i got a problem when i using mplayer to play a video

it output

VO: [xv] 560x304 => 560x304 Planar YV12
X11 error: BadAccess (attempt to access private resource denied)

if i specify "-vo x11" it will be normal,but the "-vo x11" driver can
play the video in fullscreen size...= =

i don't remember what effected this(after upgrade some ports?)but the
other things are normal.
