Can you reliably multicast out any files, or is it just with live streams you have issues?

Hi....

I am having trouble getting vlc to multicast reliably. My current setup is a 
3GHz P4 running Fedora 3. I am using vdr+streamdev to take DVB channels from 
a Hauppage Nexus-S card and then I am using a command line similar to the 
following to take a http stream from vdr+streamdev and then re-stream it as 
a multicast:

vlc http://localhost:3000/PS/14710 --sout 
'#standard{access=udp,mux=ts,url=239.255.12.42:1234}' --ttl 12

The reason I am using vdr+streamdev instead of letting vlc access the DVB 
card directly is because I found it to be much more stable this way.....with 
vlc I kept getting TS discontinuity errors and eventually CRC errors which 
would just crash or hang vlc.

Most of the time, when vlc starts, about 4-5 multicast packets get sent and 
then nothing. Every once in a while (maybe once in every 20 attempts), a 
multicast stream will start and will work fine until I have to restart 
vlc.....

I don't think it is a problem with Linux.....mp4live multicasts just fine 
everytime. And I am not sure the problem is related to the version of vlc 
either. I have tried vlc 0.7.2, 0.8.1 and cvs versions. I have also tried 
running vdr+streamdev and vlc on separate machines....same thing.

I was wondering if perhaps anyone else has seen this, or perhaps might be 
able to suggest possible solutions to this problem.

Thanx in advance.

Chris Bradshaw.
