figured it out. if there are no featured images created when you make your video, it will not display for you. you will need to set your featured image. so go to “edit” your video, then scroll down and look on the right hand side. if there is no featured image there, that needs to be filled. this should be done automatically when you upload the video, but I had the same experience as you guys, only 5 came up? i then noticed when you embed your video, the iframe code is missing the “http:” in the code, which is standard as far as I know. so I just added the http: to the code to see if that would do anything, clicked “update” to refresh. I then went and clicked “search again” under the video thumbnail tab and walah!! the featured image loaded for me and came up on the home page widget. hope this helps. here is the site I updated: https://stacybiccum.com
