I've been trying to watch a movie I bought on iTunes on my AppleTV all afternoon. I've committed the cardinal sin of moving between two different countries (!!!) so this movie is on the iTunes account in the country I lived in before. Playing it from iTunes with AirPlay it kept stopping for some reason, playing it with home sharing worked for a while, and then I tried to buy a song I liked from the movie on my computer and it stopped and lost where it was in the movie.

I got pissed off and just pirated it and used Beamer.app to send the video to the AppleTV, it played back flawlessly.

I'm happy to pay for a movie. I've funded several documentary projects on Kickstarter. Just give me an MP4 or MKV file so I can trust that I can play it today and 10 years from now on any device I own.

DRM doesn't work. It only punishes the actual customers.
