To be honest, I may be the culprit. I noticed that the undefined symbols 
were coming from GDI and the Multimedia API, so I probably added -mwindows 
as a shortcut. I have taken it out, as it (naturally) caused the console 
output to disappear.

I would have to try, but I probably won't bother. SDL is working.  The only 
reason that I installed it is that one day I decided to compile MPlayer with 
support for as many libraries as possible, whether I need them or not.

It seems to work, but my requirements are simple, and I am easily satisfied. 
  I type "mplayer -vo SDL <movie-name>". If the movie plays, then I am 
happy, and if it does not ... Right now I am happy.
