How do you watch your movies?

Soo basically all the rental stores around me have gone under, my parents won't let us get Netflix, and the on-demand movie selection on the TV sucks. They get a few new releases that disappear after a while, and they never have older movies. Now I mostly stream movies, downloading isn't really an option cause my laptop is pretty slow. Mostly I just want to be able to watch movies when I'm on a long plane/car ride or something or don't have internet. Plus I'm a nerd and like listening to commentaries and stuff, lol. So I guess what I'm asking is are there any other options that you like better? How do you watch your movies?
