Get the address to the video http://www.youtube.com/watch?v=1mxaA-bJ35s , and copy the part after v= only 1mxaA-bJ35s

Click on the youtube logo in the menu above as you are posting that will give you this

[YOUTUBE][/YOUTUBE]

Now paste the part after v= from above 1mxaA-bJ35s in between the youtube tags and you'll see this

[YOUTUBE]1mxaA-bJ35s[/YOUTUBE]

Now your post will show the video :)



If the address has more after the code, for instance http://www.youtube.com/watch?v=e4eV1QFR6HQ&feature=related, then only copy the part between the v= and the & symbol
