While I like the idea of simplifying a streaming webserver installation for people, I feel like there's a lot of work yet to be done. Firstly, the design on your demo site is not really the greatest if you have a large library. You need a way to filter (check listjs.com) and fix the Series->Overview height problem (add a fixed height + vertical scrollbar in CSS).
Lastly, there should really be a couple quick lines on your homepage explaining what this is to the average joe.
"Vstream is a php framework for managing MP4's." What?
Clear that up, move it to the left, move the latest news to the right, add a video introduction and tutorial, and you're almost there.
Keep it up. LL
