Hi eilygre
Sounds like you may not have mplayer configured for your system.
You want to have a look through the mplayer config. file - usually in %HOME%\.mplayer - and check video output is set correctly for your system.
Below is my mplayer config file, the lines starting with # are treated as comments:-
# Write your default config options here!
cache=12288
cache-min=30
#ao=kai
#ao=kai:uniaud
ao=kai:dart
#vo=kva:wo
vo=kva
#vo=kva:dive
#vo=kva:snap
user-agent=NSPlayer/4.1.0.3856
dvd-device=w:
ao is audio output; I'm using kai:dart as uniaud does not work here
vo is video output; Here vo=kva uses the SNAP overlay as it is available on my system. The commented lines can be used to force dive or snap output modes.
Maybe you should try setting vo=kva:dive as that should work.
You may also want to investigate smplayer -
http://ftp://ftp.netlabs.org/pub/smplayer/smplayer-0_6_9-b2.zip - which provides a "frontend" to mplayer but requires the qt4 runtime support files
http://svn.netlabs.org/qt4An alternative to mplayer is vlc
