Fedora 9 and VLC 0.8.6h

[GrandPA]

I'm trying to join multicast streams from my network with VLC on Fedora Core 9. In the access router I can see that the computer get a membership with the multicast group that I've chosen, but it only lasts for about five minutes (it doesn't get renewed). No picture and no sound during the five minutes it's connected.

The VLC-client doesn't display any information about the stream at all. If I run VLC on a Windows XP I get picture and I get a persistent connection (it's getting updated and doesn't disconnect after five minutes) to the stream and that leads me in the direction that it's something I'm missing about the OS here. I've disabled the firewall in Fedora just to see that's what causes the problem but there was no improvement.

And there it sits

Any ideas anyone?

Either firewalling or network card driver problem.

[GrandPA]

First of all: Thanks for the reply!

The firewall is disabled and the server is connected directly to the multicast interface, so that leaves me with a potential problem with the network card or perhaps driver? It's a brand new Dell 1950 and I've tried both of the network interfaces (same controller, but at least two interfaces ) and that didn't help.

According to the access-router it joins initiates the multicast-group and if I sniff the network everything looks alright. Compared to the traffic from the XP-client I don't find anything strange, allthough there is a lot of data to cover so everything is possible of course. Any ideas on what to look for?

IGMP not being renewed is a bug in some part of your kernel (or hardware, but Windows works so...). Nothing we can help with.

There is a new fedora 9 kernel today did you hit this problem on this newer kernel or earlier ? (what's append with the newest ?)
