How to play videos on Kurio 7 in a kid's profile


I just bought a Kurio 7s, and am new to android. I managed to transfer some videos onto the tablet, and I'm able to visualize them under the parent profile.
However, when I click on the same icon (looks like a rainbowed tv screen), I can only access the pictures taken with the camera, but not the video.

I found out that the video are stored in another place, and that the photos are coming onto a "shared" folder. This folder is however too small for video storage.

Has anyone managed to import video on the Kurio 7, and made it available in a Kid profile?

Thanks for the help,
