Trouble opening UDP stream on OS X

Hi,
I am trying to stream a live DV cam feed from a windows box to my mac. When I try to open up the stream on the mac, I get a message saying the following:
access_udp: cannot open socket
main: no suitable access module for udp://@:194
I am new to this. Please help.
Thanks
Ray

You don't provide a valid URL. the IP (either a uni- or a multicast one) before the 2nd colon is missing.

The stream is broadcast as a unicast to the UDP port specified on the machine where it is being viewed. I was under the impression that the '@' is equivalent to 'localhost'. While viewing the stream, I pick the first option which says udp/rtp and port # under the open network stream option. Your help is greatly appreciated.

The @ is an indicator for Multicast UDP instead of unicast.

I managed to change that. Now I get an error that says "Cannot pre fill buffer"

That means that no data is arriving.
You probably have an issue with firewalls, NAT or perhaps the TTL of the multicast packets (if there are multiple routers between server and client, you need to increase this value).
