All things related to multicast

[Philip Pishioneri <>]

Anyone clued in as to why I can't receive (well, most folks, as listed
at the sdr monitor site) the NASA TV announcement, and yet can receive
the data streams if I manually start them up?

Both appear to originate from the same IP address (131.182.10.250).

To save you having to look up the announcement, here's what sdr monitor
has:

n=131.182.10.250 131.182.10.250 982357190 224.2.127.254 9875 127 trusted
