Since I have had some issues with video, I tried this, and got the
following with both command lines:

[user at localhost ~]$ mplayer http://www.kozt.com/koztlive.ram
MPlayer 1.0rc2-4.1.2 (C) 2000-2007 MPlayer Team
CPU: Intel(R) Pentium(R) 4 CPU 3.00GHz (Family: 15, Model: 2, Stepping:
9)
CPUflags:  MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1

Option vo-x11 needs a parameter at line 3
[user at localhost ~]$ mplayer -playlist http://www.kozt.com/koztlive.ram

What file would it be talking about here, and what should that line
read?
