Annoying, every video on YouTube movies has audio and visual stutters regardless of video quality chosen or amount of time left to buffer. A full movie that was uploaded to YouTube by a 3rd party runs without stutters at 720p while the movie I paid for runs at 480p and has video/audio desync and sometimes has feedback during louder scenes. I'm not talking explosion loud I mean Thor smashing a coffee mug loud. Reinstalled, reupdated, cleared cache, factory reset, the whole shebang. Still fails.
