There are a couple of ways that seem to be useful.
One is to define
in
~/.mplayer/config; you might want to start with 2, perhaps try 3 and see what you get. The number is a multiplier; i.e., 2x, 3x and so on.
The best way I've found, however, is to
Code:
mplayer -fs file.name
(you can alias
mplayer to
mplayer -fs, for example).
You may want to check the manual page and fiddle with the
geometry option.
Hope this helps some.
