Can't Get my JSON Feed to Work Properly

I keep trying to setup my test channel, but I continue to have trouble with my JSON feed. I have run it through jedit and jsonlint to make sure everything is setup correctly. I have then placed my finished json file in a bucket on my Amazon S3 server. I made sure to have the permissions setup so everyone can read it and have confirmed the metadata properties are setup as Content-Type : application/json. When I upload the link to my Roku Development dashboard, it accepts it just fine, but when I go to check the feed status it tells me:

“No valid items were found in the feed”

My content is hosted on Vimeo Pro and I have tried using both the MP4 and HLS streams with no luck.

Here is my JSON code:

https://s3.us-east-2.amazonaws.com/betamaxtv2/BMTRokuEdit1.json

What am I doing wrong?

All the properties in the schema are case sensitive
Change Movies to movies.

Wow! That got it working. Thanks!
