Mplayer Question
 

I want how to make the movie in mplayer to be fullscreen ,but not the option from the GUI fullscreen,but the very movie :)
Thanks in advance

the very movie?

you've provided no real useful information, but questions abuot fullscreen come up generally when you're using x11 output, rather than xv, xover, or similar. try using xv output, and if that doesn't help, use the -zoom option to make x11 run fullscreen correctly.
