I am using the plain yogurt theme and have added the basic youtube block that comes with it. Everything works fine, except I need to remove the related videos at the end. It can be a blank screen or anything, doesn't matter just not the related videos.

I know the code has to have ?rel=0 at the end. However, I figured out that the block won't accept the ? mark through the normal editing. Does anyone know how I can hard code it? I tried the view.php in the youtube block in my cpanel, but nothing seems to work.
