Why does it take so long at the beginning and when the stream starts you can jump anywhere and the stream is loaded almost directly?
As you can see in my video, no data (e.g. the video) is downloaded when the user is waiting, but only when the stream really starts the video is downloaded.
I think your hoster is really good, just wonder what this loading time is supposed to do, if your server saves the file, should it be able to output it directly? If you can fix that, then a lot more users will use your host.
