Hi Ruben, I see that you have done it, but more importantly, how did you do it; as both Bruce (site owner) and I have tried and failed using the 'Media Tag'
This is how I normally do it:
I find a Youtube video that I wish to embed on our forum. I click the 'Share' button and then the 'Embed' button. I then right click and copy the code string....I then paste the string directly into the post. If HTML is enabled (which it is for Admins and Global Mods), I then click 'Preview' and the video appears...click submit and all done.

Could you please tell us how you do it using the Media Tag, as we must be doing something wrong.
Kindest Regards and many thanks for you patience,
Darryl
