Hello, Unfortunately, we don't fully understand you... please. provide us with more details regarding the issue.
Instead of selecting and clicking on a video to make it run ever time you want to play it, an option, able to select or set something that allows it the same video to run over and over again by itself.
If you have the opportunity, take a video of what exactly is going on and send it to us. Thank you.
If you go to youtube.com, find a video you like, right click on the video after you start it, you will see "loop" which means it will play over and over and over until you stop it. See attached screen shot for reference.
