We have installed a site update few days ago which allows one to even more easily install embedded videos in regular board messages.
Details are posted in section:
HOW THIS SITE OPERATES QUESTIONS under topic:
How to post videos in regular message posts TOPIC
To sum it up, here is the easy way: You will still need to have your videos posted on a outside site, such as Youtube, Facebook, Vimeo or others. After posting your video on outside site, copy the videos URL on your keyboard. Then when you are in the regular forum and click on "NEW TOPIC" add "subject" then start typing
your message in main body. Then:
1) You just type in main body, what ever you want, then when you want to post a video just hit return button and paste the URL link from your computer keyboard. Then hit return button and continue typing. That is it!
Your messages will open as embedded! 
More details are posted in HOW THIS SITE OPERATES QUESTIONS section.
The other technique will still work too!
