Video Upload & Play inline the Topic - how to?

Hi all. Video Upload works now fine, but to made the Video run directly in the message-window is a bit "frickling" - because of Forum-Software.. 
Here's the "How To":

1. Open a new Topic or edit an existing one
2. Upload your Video (.mp4 only, max File-Size 20 MB) - just use the "Add Files" Button
3. Place the curser in your topic where the Video should appear later (mostly under your message..)
4. Click ONE time the "Insert" Button
5. The video will appear in embedded player & as a LINK under your topic if you're NOT LOGGED IN.
6. If you're LOGGED IN, you'll see just the Video-Link.. but ofc you can click on 'em & watch the Video 
   

Here an example - Sandy on the run - but I got em anyway..
