I knew I had done this for a reason. of course i don't argue that it  
doesn't break demuxdump.
I couldn't remember anymore, but today I was playing with MBONE  
streams and suddenly it all became clear again. The problem is that  
quite often MPEG-TS is NOT autodetected. VLC thinks the material is  
PS. Starting the stream over usually fixes the issue. It might be  
related to the fact that it takes a while (couple secs) before the  
multicast stream is setup/being received. Perhaps this makes the TS  
demux bail sooner?
