It sounds like you’re talking about Streaming Quicktime. If that’s the case, the movie files need to be on their own subdomain. You can keep montage.etownedit.com for those pages, but put the .mp4 files on video.etownedit.com (or another subdomain name) by going to the Panel under Goodies and set up Media Streaming.
I’ve used Streaming video before, but have used .mov for my file extensions. I don’t know if that matters or not. I then gave up on that and made non-streaming videos since I wasn’t able to get the right combination of size and quality for streaming and I didn’t mind if people downloaded and kept the videos.
