RTSP?  Is this why I cannot play video on C-SPAN's Site?

I guess this is more a personal question than a professional one.  

Whenever I try hitting any of C-SPAN.ORG's video links, I get a "Cannot find
server or DNS Error" instead of a web page or any video.  I noticed the
URL for the video links I cannot view begin with rtsp:// instead of
the usual http://.  Videos on http at C-SPAN.ORG work fine for me.

So, I googled RTSP and found out it stands for Real Time Streaming Protocol,
which sounded relevant.

The help pages on CSPAN.ORG emphasize having the latest Real Player,
which I verified I have.  

Here is a sample link I cannot view:

So, do I have to buy a MAC to watch these videos?  Please save me
from that humiliation. hahah  ** just kidding **

Any pointers extremely appreciated (except toward MACs please).


p.s.  I hear MAC G4s are the best microcomputers made, and I believe it.  My problem is lack of money, not lack of interest in MACs.  Thanks again.

    Most likely, someone (apparently with appropriate authority) has configured your Internet connection not to permit TCP sessions using the RTSP service port (which I believe is 554).  You may or may not be able to obtain an amendment to this policy; it will be easiest if you're the one with the keys to the firewall.

    I own the firewall, here at home.  So I just need to get port 554 opened?  How do I do it?

    I found the solution.  Just a setting in Real Player, to associate Real Player with RSTP.  Under Tools-->Options.
