Here's what he did: He had the sub-d in "polygon" mode when he bound it to the skelton. Here is another fix. Unbind the object from the skelton, delete history, then rebind. The only drawback is that you'll have to look at the poly box thing around your object while in perspective view. It won't render out that way.

Just remember to right-click your sub-d's and make sure they're in regular object mode before you bind them.
