What I think is that the conversion with Quicktime Pro produced a file 
that is not suitable for streaming. The file does not repeat certain 
MPEG headers for audio enough, so that the client gets confused when the 
file is streamed. I am not sure because VLC just tries to correct these 
things.

A test could be to convert the original file with VLC? Or is it in a 
format VLC does not understand?? 
And then stream it using VLC and see if it has the same problems.
