Andre, when i working on the field my eth0 or any other network interface is down then i think the multicast route to an DOWN interface will not help.

in the hotel i use wireless network and this is the routes active:

address@hidden:~$ route -n
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface
0.0.0.0         192.168.0.1     0.0.0.0         UG    0      0        0 wlan0
192.168.0.0     0.0.0.0         255.255.255.0   U     9      0        0 wlan0

It sounds like maybe you just don't have the multicast route setup.
Try executing in a terminal:
route -n
if you see a route to the multicast subnet (224.0.0.0) you're good.
I'm guessing you won't.
Run:
sudo route add -net 224.0.0.0 netmask 240.0.0.0 dev eth0
Then try again. If the network interface you are on is not eth0 replace appropriately in the above route command.
