I had been looking for a solution to set up CloudFront private streaming videos on a membership site for some time when I came across S3 MediaStream. I decided to give it a try and it proved to be a good decision! This plugin really does the trick. I had my first private streaming video playing in 10 minutes after solving the issues with CloudFront Streaming distribution first. And I got good customer service from Rudolf, he was willing to assist me over GoToMeeting when I was struggling with AWS. The result: I am now moving all videos + pdf documents to AWS and offer them with this plugin to customers for viewing and downloading.
