That's the problem: the RTSP server says that - for some strange reason - 
it can't do standard RTP unicast streaming.  I.e., the problem is with your 
RTSP server.

When I try opening

the server reports:
         Server: Kasenna MediaBase version 6.1
So, you should ask "Kasenna" why their product is non-compliant.

Not very.  I'm generally disinclined to support non-standard protocols and 
formats (although if Kasenna, or anyone else, is interested in paying my 
company to do this, I might consider it :-)
