I fixed my own problem, for anyone out there. I used CSS styles to force the video into a box. Here is the code.
.featured_video_plus {
position: relative;
padding-bottom: 52%;
padding-top: 30px;
height: 0;
overflow: hidden;
}
.featured_video_plus iframe,
.featured_video_plus object,
.featured_video_plus embed {
position: absolute;
top: 0;
left: 0;
width: 100%;
height: 100%;
}
