[issue12373] Duplicate packets in Multicast Receiver

[Aleksey Zhurbitsky]

New submission from Aleksey Zhurbitsky <zhurbitsky at gmail.com>:

I use http://svn.python.org/projects/python/trunk/Demo/sockets/mcast.py to receive multicast stream. When i run one instance of this script to receive certain multicats stream all is fine, but when i run two instance of this script simultaneously to join different multicats stream whith same port - starts mess. Each script gets his packets and packets from other multicast group.
Examples of multicast groups:
rtp://224.1.1.1:1234
rtp://224.1.1.2:1234

I also try to use other code to recive multicast but got the same result - http://stackoverflow.com/questions/6387535/duplicate-packets-in-python-multicast-receiver
