there is an IGMP membership report issued to join the group I have
specified for any sources.<br>

However, when that first (and only) client tears down the session,
there is no IGMP membership report for the 'Leave'.<br></div></blockquote><div><br></div>That's correct, because the "groupsock" object (the member variable "fInputGroupsock" in "MPEG2TransportUDPServerMediaSubsession") is not destroyed at this time. Instead, it stays around to be reused the next time that "createNewStreamSource" is called. That's why I'm confused as to the behavior that your're seeing. I'll have to investigate...</div><div><br></div><div><br></div><div><blockquote type="cite"><div bgcolor="#FFFFFF" text="#000000">I suspect that the lack of an IGMP leave in the source destructor
may be the cause of this unexpected behaviour.<br></div></blockquote><div><br></div>No, because if - as in this case - the "groupsock" object is not destroyed, then it should be OK to reuse it for new "BasicUDPSource" (or "SimpleRTPSource") objects.</div><div><br></div><div><br><blockquote type="cite"><div bgcolor="#FFFFFF" text="#000000">Would you suggest I write my own subclassed source and destructor,
