1. First log onto youtube, pick the video that you want on your profile and go to the share button.
2. Click embed. It should have a tickbox that says "use old url/link". If that is not there anymore then just click the url in the code box and copy and paste it to a notepad.
A).Now if the old link was available then you would simply copy the code that comes after "www.youtube.com/v/" and stop copying when you get to "fs=1".
B). If the old link was not available then you can still use the new link, by copying the code after it says "www.youtube.com/embed/" and then stop just before you get to "rel=0"
4. Now where I have put all the "XxXx"'s, just replace that with your code.

Now that you have done this, you next options are:
1. Auto play
: If you don't want a video to autoplay, delete "&autoplay=1" from the embed code.
: Change the height and width to 0 to make it invisible. Mess with the heigh/width until you are satisfied.
