which ethernet adapter are you using? (some cheap ethernet cards don't
support multicast very well).

you can also set a "default multicast route":

 route add 224.0.0.0 -netmask 0xf0000000 -interface ${hostname}

but should not be needed if you have only one ethernet card.

mrouted is only needed if you have multiple ethernet cards, or you
are creating a DVMRP tunnel through a router to another network.

I suspect the problem is in the ethernet driver not supporting multicast
correctly.
