Mat,

Thank you for your response.  It seems though that the rtsp server at 
the location is made for Linux, though.  I am going to look through the 
code to see if it should be very difficult to port it to work on Windows 
though.  If anyone else knows of where I can find a version of rtsp 
server that works with Windows it would be greatly appreciated.

William
