Actually I have not said that I checked that multicasting is working, but that it is enabled on both machines... 

The results I get are the same either that I specify the default ip multicast address or not.

How could I verify that multicast is actually working? If it was not working then how the two machines could see each other?

How is the default route determined if multicast is enabled on both adapters?
I am not experienced with multicast configuration yet, I was under the
impression that you need to define a default route for multicast traffic,
and that would not work well with multiple adapters enabled for multicast.
Maybe off topic if you have verified it is working.
