I was driven insane by trying to work out how to embed for Youtube and Liveleak. I now know how to do both, and wanted to record for other people so they would not similarly be tempted to start self-harm in frustration.
Youtube
1. Go to the Youtube page you want. Cut and paste the URL from your browser exactly as it appears, like so:
http://www.youtube.com/watch?v=cVHLvtArC_g
Ok, now:
Note the following, use the remove link button as follows: thats the world with a small paperclip underneath it. Cut and paste into word also works.
http://www.youtube.com/watch?v

Now, I have bolded and coloured red the bit, that you need to remove. It was hard to see the bold for the equals sign, so i made it larger.
Now,
remove all the things that are in RED and put a forward slash after the 'v' - a forward slash is / for those who dont know.
So you have the following:
http://www.youtube.com/v/cVHLvtArC_g
Then add [embed] at the front. You need to put a forward slash in front of /embed at the end and close it with brackets.
