The self-proclaimed PhotoshopGuys released the first (to my knowledge, and googling) Photoshop Vodcast (thats what the kids are calling it, at least.) In the past, they've had podcasts, but the addition of a visual medium really makes the Vodcast worth watching. In the first episode, they cover sharpening, which doesn't really translate that well to ultra-compressed video, but its a good overview. Check it out, you might learn something!
