The approve button in admin has nothing to do with them, if you want to get rid of the innoppropriate and feature this video buttons do this:

In View Video.tpl FIND THIS:
<DIV style="FONT-SIZE: 12px">Flag this video: Feature This!
Inappropriate

REPLACE WITH:
<!-- <DIV style="FONT-SIZE: 12px">Flag this video: Feature This!
Inappropriate -->
