Sure! I love kettlebells, love talking about kettlebells, own up to a 53 lb kettlebell
There are a lot of good/bad videos out there on youtube but I've found some good ones.
Crossfit includes kettlebells in their workouts and they have a good video on the kettlebell swing. They show you what a good kettlebell swing looks like and a bad one. The bad one looks similar to the one shown in Angie miller's video clip.
Crossfit also has a number of video demos but since they aren't pure kettlebells, you'd have to look through to find the kettlebell ones.
I love Art of Strength. The premier kettlebell certification is the RKC (Russian Kettlebell Certification) which means you have to be able to demonstrate and teach kettlebell movements. The owner of Art of Strength is a holder of that cert. Luckily for us, he posts videos on form on his website:
He also sells videos. They are a bit more pricier than normal videos but their production quality is good.
DragonDoor is run by the guy that is credited for bringing kettlebells to the US, runs the RKC cert and they have a number of DVDs on their site. They are all good but the production quality isn't so great. I have "The Kettlebell Goddess Workout" which is really good but wow production quality is lacking
Basically, they recorded a bunch of moves and then put them together into focused workouts. So they may have 10 kettlebell moves but put 5 of them in one workout, 5 in another, some may overlap, etc.
And in terms of more mainstream workouts, I recommend the GoFit ones. (Just don't tell my Crossfit buddies that I said that). I think they introduce kettlebells in a friendly way that appeals to the masses. The thing they don't apparently tell you is you will need to increase your weight.
