With your file manager right click on a movie file and select properties. 
Click on the button with the wrench icon beside the file name. There you 
can add Mplayer (if necessary). Then move the Mplayer line to the top to 
make it the default. Click on the modify button and select the program 
tab. Probably the command is "mplayer %u" or something similar. Change it 
to "mplayer -fs %u", i.e. write "-fs" after "mplayer". Then Mplayer will 
always start in full screen mode. It will keep the aspect ratio of the 
movie and put black bars to the top and bottom or to the sides if 
necessary. Finally click "OK" to apply the changes.
