Embedded Video – no related vids at the end

Hi. I'm embedding a youtube video on my site from a custom field. I'd like to show no related vids at the end of the youtube video. this is the line of code in my content template:

[types field="merchant-video1" width="60%"][/types]

i've added &rel=0 and &rel=0 after the code and rel="0" inside the shortcode but it doesn't stop the related vids from showing. Here is the url of and example page:

how do i add the rel=0 code to stop the embedded vids from showing?

Thanks.
