Additional info:

The behaviour described above (no mcast traffic) occurs only if not 
using a config file and therefore streaming the full mux. I've now tried 
the same setup but specifying services in a config file and don't have 
the issue. Hopefully that should narrow down the cause of the issue.

Cheers,
