Hi Joel,
I tried it both ways.
I uploaded it. Then right clicked to "make public" then copied the link and put in into the url where I took out an old video url that was from another hosting place.
I wasn't 'sure if I had to use cloudfront or if I can just use the url. The video worked when it was at another hosting location before trying it on amazon s3. It's encoded with handbrake and is an m4v file and it played on the roku device (from the other hosting location).
Thank you
