Nope. The movie studios will only allow certain movies on there and certain quantities from certain time periods, and when hbo is showing a movie they has exclusive rights so it can't be on any streaming service. It's all very convoluted. I'm sure a lot of stuff is on there pretty permanently, but a lot of the newer/popular stuff is cycled in an out. I remember when they signed the deal with miriamax, the rotation was a big deal.
Most Tv shows seem to stay on forever though. We been watching phineas and ferb for years on there. YEARS.
