Oh whoops. VIDEO collage xD
I'm dumb
Well here's my older posting
There's various collage makers online, although might be hard to find a good one.
Perhaps use an online program like pixlr, make a big enough canvas, load up images and move em around.
Take screens with windows default Snipping Tool of the videos/DVDs
edit: i'd start with a really big canvas. when you load the images, i think you have to rectangle seelect them, edit copy, then paste them onto the canvas
