Apologies for jumping in the thread, but when mplayer spews something like 
this, it usually contains some useful information about what went wrong. I am 
no expert on mplayer, but see two possible issues here:

What video card do you use? What does "lspci -v" say? What drivers for the 
card do you use? Do you have an /etc/X11/xorg.conf file or not? Did you 
customize it in any way? Do you have Compiz or KDE desktop effects active?

N.B. Most modern graphics cards with appropriate drivers should be able to 
support xv. If mplayer cannot use xv, usually something is very very broken 
somewhere in your video setup.

So did you try it?

mplayer -vo x11 movie.mov

You might wish to add also the -zoom option to be able to go fullscreen. It 
can also be useful to add the -framedrop option if you have a slow system, x11 
video output is software-based, uses a lot of cpu power.

I am not very familiar here, but it seems that the movie native resolution is 
2624x2112, which is extremely big, so mplayer is using the software scaler to 
reduce the size of the video in order to fit on the screen. But the software 
scaler also has a compile-time maximum width it can handle (2048), which is 
also less than 2624, so it fails.

In other words, what kind of a movie are you trying to play? The resolution of 
2624x2112 is way, way too big for any typical movie. Did you try to play it on 
another computer (possibly with a different software and OS)? Does it work?

More importantly, is this error specific to this particular movie only? Try to 
play some other, known-to-work movie using mplayer (both with and without
-vo x11) and post the output if it also doesn't work. Or if it does work, then 
the file you are trying to play is badly broken, and that is an entirely 
different problem.

HTH, :-)
