My cats and my television don't mix

So, we had an interesting incident today: I plugged in my TV and DVD player for the first time since the kittens moved in, and put in Wallace & Gromit: The Wrong Trousers, both to see what the cats would think of the TV phenomenon and because I enjoy the movie, and hadn't seen it in a while. Shadow, the more confident (much more confident) of the kittens sat at the foot of the TV stand and watched. I picked her up for a brief period, and held her close enough to the screen to touch it, she pawed a bit at the images, and all seemed well (Smokey was further off, as was to be expected, he being somewhat timid). But when I moved their cardboard scratching post, which lives at by the TV stand, Shadow jumped as if startled. A minute later I accidentally touched her, and she leapt again. This is a cat that hasn't been more than mildly startled by anything else so far. So the TV is off, and will remain so in the short term, if not the long term. Ditto for the Playstation.

This is probably a good thing, given how much time I've spent in front of the thing.
