Well it's not really broken. Consider for example that you could use a
different vo for each file:

mplayer foo.avi -vo x11 bar.avi -vo xv

In that case, it's necessary to uninit one vo and init a different one
for the next file. Keeping the window between one and the other
*could* be possible, if a separate X/window creation layer were added
that all the X-based vo's would use, but like I said it would be a lot
of work.

In the case of keeping the same vo between movies, it wouldn't be
quite as hard, but mplayer would need to be aware that the same vo is
being used, and avoid uninit and reinit in this case. Further, the
vo's would have to be fixed not to crash if their config function is
called more than once to change parameters. Most vo's are broken in
this respect, or at least they were last I checked.

Hmm, do you mean that the mplayer *window* (with decorations and all)
stays on top when you switch desktops, or just the movie image? The
Stealth64 doesn't even have overlays, so I assume you're using -vo x11
in that case. Please submit a full bugreport as this seems like it
could be a real bug in mplayer.
