h264 and multicast bug

[vsai]

I use vlc 0.8.6c.
I'm encoding with x264 a stream. I want to relay this stream using multicast.
If I start the vlc server first and then the vlc client I can't view the multicast stream.
But If I start the client first and then the server, then I will see the stream.

I start my server with this command vlc -vvv http://86.107.248.12:8082 --sout '#standard{access=udp,mux=ts,url=224.0.0.3}'.
The stream cames in h264 format. If the stream is not h264, the multicast will work fine.

Could this bug be solved in cvs?
Thank you.
