mplayer confusion -- no gui?

Hi All,

I have been playing with mplayer. I think I am
missing something. I get just a command line utility.
No volume adjustment, no gui controls of any kind.

If I run a video DVD (mplayer /dev/dvd), I get
a video screen with no controls (no sound either!).

If I run streaming audio from the web, it works
fine, but again, it is a command line terminal
with no adjustments.

Is there suppose to be a gui interface for this thing?
What am I missing?

Many thanks,

rpm -qa \*mplayer\*
