Just got your private message.
I got the impression you were paying us for media hosting, but I now see you are trying to host this video media file on your own web server. We have no control of your web server, there's not much we can do for you unfortunately.
Essentially 2 things are needed: 1) The file is saved stream-able, see Mikes comment above how to do that and 2) The service you use to host the media can serve the file stream-able, which means it supports multi-byte range requests and byte serving.
Our paid media hosting service does serve the media stream-able, but we do not touch your media files. Our service is pure, meaning what you want us to serve is what we serve, we don't modify it in order to save costs.
I also downloaded your 233Mb video, and it still not optimized for streaming. You'll need to re-go through the steps, or do a Google search to find instructions how to make your video stream-able or re-review the link Mike posted above to see what you did wrong.
