1. You can make any video link full screen by changing the video id part of the this link format (highlighted in red)


https://www.youtube.com/embed/NMx2jj9Ye70?autoplay=1&showinfo=0

 

2. And you can force Youtube to only recommend our channel by :


If there is already a ? in the url, then the change you make is different.


For instance, if the url is this:  https://www.youtube.com/embed/8Qpv_lR1bI0?wmode=opaque
Then, you add &rel=0 (ampersand instead of question mark), to get this https://www.youtube.com/embed/8Qpv_lR1bI0?wmode=opaque&rel=0

The rule is: 
If there is no ? in the url, then add ?rel=0 to the end.
If there is a ? already in the url, then add &rel=0 to the end.
