What's probably happening is that you have a firewall somewhere 
(perhaps Windows XP's built-in firewall if you're running that?) 
between the server and client, and this firewall is blocking RTP/UDP 
packets - i.e., the audio/video data coming from the server.

Either fix the firewall (preferred), or else add the "-t" flag to 
"openRTSP", to tell it to request RTP streaming over TCP instead of UDP.
