I worked on a Linux system and had a similar symptom for a couple 
different problems.

1. The first problem was the multicast configuration of the network.  On 
my system it worked if we enabled IP forwarding and also enabled multicast 
specifically.  I combined all the suggestions I'd seen on this list and 
websites, and this combination of commands solved the problem on my 
system. (Although there could(?) be some security issues with enabling IP 
forwarding; I couldn't really say whether or not it's a "good idea.")

$> su root
$> /sbin/route add -net 224.0.0.0 netmask 240.0.0.0 dev eth1 
$> echo 1 > /proc/sys/net/ipv4/ip_forward
$> /sbin/ifconfig eth1 multicast
$> netstat -r -n

2. The second problem was that after a software update, the "camera" I had 
began sending RTP packets which indicated they were RTP version 1.0 
packets and not version 2.0 packets.  The RTP packets were being discarded 
because they were mis-labeled. (I'm not sure if this was LIVE555 behavior 
or the behavior of some other part of our system now.  It's been awhile.)

Good Luck!
