I am using the youtube plugin of NoahY.
As I have set up my videos to appear quite large in the answers, it does not look good in the comments (there the youtube code is parsed as well).
To change sizes of the youtube player in the comments, use the following css:
.qa-c-list-item iframe { width:400px; height:330px; }
