Erm, I think you might want to stick with a GUI video player for now... You don't seem to understand the first thing about GNU/Linux...
the /path/to/files/ part is a commonly used way to say the path to the files you want to play. For example /home/zaurus/Documents/file.mp3 or something like that. If you're gonna try to use a command line app, try to first get basic Linux system layout and usage abilities.
