@ wonderbreadSTS you bet me to it, your way is alot faster. There should be a sticky to show how to embed vid's.
Here's how you put youtube vid's on the forum:
1. Click "share" under the video on YouTube.
2. Click "show options".
3. Click "long link".
4. Copy the link that comes up
5. When creating your post/thread click the "insert media" button and paste the link in the box
and you end up with this:
