Keylight humming on edges

I'm about to go nuts. Here is the down and dirty.
• Greenscreen Footage shot on HPX 170 720P DVCPRO HD. Shutter at 60 (slow motion.)
• Using After Effects CS4 on Mac Intel quad core
• Using Keylight to key
• Greenscreen lit well
• Subject lit well
Over all it looks good. Now when I apply keylight and try to fine tune the hair edge on the subject (talking head at desk) the hair edge is humming like a bitch. Persons Hair is not frizzy. The subjects arm and hands and upper body edges are looking good. Subject moves a bit but not much.
Have tried a garbage mat that didn't do anything
Tried exporting the footage to 8 bit uncompressed and/also Animation from QT. Got the same results when reimported to AE and keyed.
Is there another way to sharpen out these hair edges?
