Im sure this has probably been done a number of times but I was wondering if anyone could point me in the direction of an AE tutorial.

I have a video I want to create and the opening scene will be me and a friend sitting on the sofa watching the TV.
I will then video the TV and zoom in to the screen. Now this is what I am wondering how to do. How to make it look as if I have gone through the screen and in to the video.
I imagine with some sort of bending effect of the screen...does this make sense?
