You likely need an igmp querier on the network to refresh
the igmp memberships.  Multicast routers can do this, and
the better managed switches can be configured to perform
the function.  Some "smart" switches can do it, although
some are not quite smart enough (they depend on
other devices such as your router to do so).  There are
a couple of igmp query daemons floating around the
'tubes that you can run (written in perl, python, c,
probably others) if you do not have the functionality in
your routers/switches.
