The original files are all in QT of some description. 

Some of them are were created using LiveStage Pro, exported as QT movies
and then converted to MPEG-4 with QT pro.

It would seem that vlc doesn't fully understand the format of the files.
On starting vlc (attempting to stream the files) it issues the following
warnings:

I'm not sure whether these warnings are connected with the lack of audio
on the client side.

BTW these files stream perfectly from the same server using Darwin SS.

Thanks for the help so far with this.
