Hide related videos from Youtube

I want to hide related videos from Youtube. I have added a row with 2 columns. The row settings are standard, collapse Order is Default and Bottom Margin, Gutter and Padding are left empty.

I have try different methods:

1) SiteOrigin Video Player
a) I have added ?rel=0 after the link
b) I have checked oEmbed (I also tried to uncheck to see if made a difference, but the results were the same)

What I got:
The Columns overlap if I make them smaller
The Related videos from Youtube still appears

2) Embedded Video (PB)
a) I have added ?rel=0 after the link

What I got:
The Columns are proportional when I make the window smaller and it doesn’t overlap
The Related videos from Youtube still appears

3) Text widget
a) I click share> embed from Youtube
b) Unchecked show suggested videos when the video finishes
c) Copied the code from Youtube
d) Past the code into the content area

What I got:

The Related videos from Youtube does not appears
The video gets trimmed and there is no gutter separating them.
The video on the right seems bigger than the one on the left.
There is a huge gap on the left side and all the row seems to be attached to the right.

How can I hide Related Videos from Youtube and maintain the layout?

Thank you!
