I'm using Fireworks to make custom belts, and I capped using CaptureWizard (I was gonna try Fraps, but it required a hotkey to start, and I ran out of usable keystrokes).
I put it together in Windows Movie Maker.
I use Photoshop to make my "Beltensteins", where I cut together actual belt plate pictures on actual leather pictures to make belts (mostly for e-feds).
Any special shape manipulation I want to do gets done in Illustrator.
I'm also trying to become a legit belt designer (like with Top Rope Belts or Parks-Millican-Mann), which is why I practice, practice, practice.
