"Stream Not Found"…

Hi Forum Members,

Maybe you can help me with this. I am using amazon s3 cloudfront. I triple checked the settings and I think everything is okay as far as the keys, etc. is concerned. However, the videos I would like to stream come back with an error message (Stream not found)..

Here is an URL with login information. After you’re logged in, click on the URL and try to start the video.

I would appreciate if you guys could point me into the right direction. Thank you very much for your help in advance.
