MU admin capability to embed videos

I have a MU application where I have to allow admins to embed videos. Currently this feature is only available to super-admins. I’ve tried the “Unfiltered MU” plugin and it does allow admins to embed videos but also would allow them to post other html, Java script, Malicious code, etc. into their post as well. Any suggestions for allowing video embeds without creating such a huge security issue?
