Quicktime Streaming Server Question

Hi, I'm not sure where to post this (as I am new to this forum) but I have a question which I hope someone can answer.
I am writing a web application that adds scheduling capability to the QTSS server at the company I am working for. It works well, except it seems the QTSS needs to be updated with the new playlist file.
Basically what happens is I tell my app to play a 3gp movie at a certain time, so when that time arrives, it appends it to the playlist file (lets say movies.playlist). When I enter into the QTSS Web admin page's playlist editor, it shows the correct entry, etc. but the server just skips my movies that I've automatically added.

Does anyone know what I should do to update the QTS Server?

Thanks
