Image Ready Question

I've recently been trying to learn how to animate avatars through ImageReady, but I've only done it once. I would like to learn more, and I have found tutorials for animating (and very good ones, they are), but they all mention this: File --> Import --> Video in Layers/Frames or something like that. When I look in that section on my ImageReady (it's the one that came along with Photoshop CS2, so I'm not sure if that makes it ImageReady CS2?), all I get is Folder as Frames, Variable Data Sets (which cannot be clicked), Twain Acquire and Twain Select. Is it a glitch, or is the Folder as Frames command really the one?

Thanks for taking the time to read it, and any help is appreciated. ^^
