After going to my command line i typed dir, that brought upa list of directories and files that were on my hd.

The file was in /home/Ben/MPlayer

so I typed cd MPlayer and now I was in the MPlayer folder, there I typed

./configure after it going through a lot of text across the screen I typed make install, after which it gave me errors of libstd headers not installed, and some things refering to error 1 and error2.
