I think we are talking about different applications. Could it be that you 
originally meant Kmplayer or Gnome-mplayer instead? When I right-click on 
a movie playing with mplayer (without any extra options) then nothing

With mplayer you could use the space key for pause. Somehow the mute 
option (key m) doesn't work for me. However the appropriate keys for 
volume, mute and pause on my multimedia keyboard do work. But I don't 
know how to change the aspect ratio while playing a movie. If you aren't 
using the full screen mode (option -fs) you can resize the movie if you 
drag the border of the mplayer window with the mouse.

I found it in the man page. Use the command "man mplayer" in a terminal to 
read it or type "man:mplayer" in the konqueror address bar. You might as 
well install the package mplayer-doc and read the 
file /usr/share/doc/mplayer-doc/HTML/en/index.html with konqueror.

And about your other mail: "mplayer -monitoraspect 16:9 %u" is what should 
be entered as the command in the configuration for the file association. 
If you use it to start a movie from the command line it would be the 
filename instead of the "%u".
