Como impedir o player do YouTube de exibir vídeos relacionados?

How can I stop the YouTube player from showing related video thumbnails and links? I am in search of YouTube video code that shows only the videos in our YouTube stream, i.e., only the videos we have uploaded.

1. If your URL contains any parameters then add &rel=0 at the end of it

   i.e., http://www.youtube.com/watch?v=joYtqNtZe6w&feature=plcp then add &rel=0

   so for example check at last

   http://www.youtube.com/watch?v=joYtdfdsNtZe6w&feature=plcp&rel=0

2. If your URL does not have any parameters then add ?rel=0 at the end of it

   i.e., http://www.youtube.com/embed/joYtqNtZe6w then add ?rel=0

   so

   http://www.youtube.com/embed/joYtqNtZe6w?rel=0
