Only the top half of the gui is showing, when I move it it goes all blury.

I have tryed reinstalling mplayer from the mandrake disks + rm .mplayer +rm /usr/share/mplayer

I have tryed to install mplayer using packages from PLF, this took me a while finding all the disrepencys. Only 1 rpm i was accually find and install (because it was not there in the sources)

How do I get mplayer to function correctly? It is anoying me

No I will not use another gui player unless it is better than mplayer

if its the video output itself that gets messed, then its probably a problem with the video driver

luckily mplayer supports (probably way to many) video output devices

type

for a small list of the outputs, then run mplayer using different video outputs untill you find one that suits you best (xlib, xv, gl, gl2, sdl are the normal ones, the rest are special ones for special cases normally ... O and dont use the drivers that sound like picture formats (png, jpeg) as these just output all the video into separate images in your current directory)

No there is no problem with the video, only the gui.

well that sure is strange as mplayer has no real GUI ..

try using mplayer from the command line and see if whatever happened happens again?
