[mythtv-users] Mythtv Backend, upnp and hamachi

I got a problem here where the upnp packets are always sent on the
ham0 (hamachi) interface in linux. Although my routers are fine for
all multicast to go out eth0.

Anybody knows why Mythtv doesn't bind to the proper interface? Anyway
to force it?
I added the 239.0.0.0 as well, but that makes no difference since
224.0.0.0 was present... Was checking somebody's post.
