MAJOR PROBLEMS

I'm using this tutorial, and I have a question because I'm getting pissed off.

When pasting the mini-movie image..I click it, and paste it, but when I try to move it, it won't move the mini-movie image...it moves the previous layer..I also don't know how to paste an image as the mini movie layer..and I'm getting mad. This may not make any sense, but I am so confused right now, and everything I try doesn't work.

PLEASE, PLEASE help!
