HBO TO GO or other streaming services?

I downloaded the HBO to Go app to my iPad and can watch HBO movies and shows anywhere I have WiFi. Awesome!

Does Showtime have an app like this? Or AMC? Or are there any other good streaming services I can use? (I have Netflix too, but don’t have Hulu+ or Amazon Prime).

Curious what you guys and gals are using, especially when you’re not watching on a physical TV.

It’s awesome to have the iPad on the trainer or treadmill. Knocked out 45 easy spin minutes today at lunch (recovering from NYC marathon) reading Game of Thrones. Lately I’ve switch between reading, watching some show or movie, or playing this ridiculously addictive Army of Darkness app. Time flies and I get a solid workout when I can’t get outdoors (and winter is coming, haha).

Also, is there an easy way I can get the movies I already own on DVD onto my iPad?
