I found this same video when I was doing the brakes on our 05 Magnum R/T. Big 13.5" rotors and dual-piston front calipers, and those rotors were like welded on. Even though I was changing the rotor, you don't want to beat too hard because you can damage the suspension.
I just did this again when I was changing teh RF hub bearing on the 01 GP GT. In this case I was saving the rotor and didn't want to beat on it at all. I spray a little PB blaster into where the rotor sits on the hub, to help it pop loose.
This technique works like a charm though, thanks for posting.
