I've recently jumped from the iOS ship to android and found out like many others that the movies/tv shows I bought on the iTunes store wont play on my Galaxy S3. Its not a big deal as I don't have that many videos, but its still a hassle. So whats the best video store (iTunes, Amazon, Play?) that will give me a straight mp4 video that can play on both ecosystems. Its annoying that I have to purchase a movie twice to play it on all my devices.
