[j-nsp] Multicast config in ERX-310

[F J]

Hi,
A big thanks to Terje!

I came to work.... sniffed with Ethereal... Saw that TTL was equal to 1 as 
he ... Banned VLC GUI for a couple of minutes :) and started the Multicast 
stream from the CLI instead... Works like a charm!

My problems had nothing to do with the ERX in the end...
