Jaggies when Chroma Keying Green Screen

Hello All, looking to see if there's a solution to a jaggies problem I'm having. Link of video file: be kind I'm shooting this Green Screen in my home office.

Formats attempted:
DVCPro 50
DVCPro HD 1080i - Best Result

Final Sequence:
Betacam 8-Bit Uncompressed

Panasonic HVX-200

Lowell DV Pro 3 point lighting kit. Light Amber gel on back light.

Final Cut Pro 6
After Effects Pro 7 with Keylight

Problem: jaggies occur on movement and curves.

Solution: want smoother edges

Attempted using keylight in AE and chroma keyer in FCP. Both key out the green fine but leave jaggies on the arms and shoulders. Tried softening, suppressor and others. Looking for a clean key. Any suggestion to filters, techniques using above mentioned programs would be great.

I've always had better success chroma keying in AE with the COLOR RANGE and SIMPLE CHOKER filters than in Permiere.

Take a look at my examples:


BTW, I've rarely gotten a clean key with the COLOR KEY filter in AE.
