I really am not sure if it is the app or what it is. When I stream video on certain apps I get good quality. Like Netflix and Hulu. When I try to stream HBO and Showtime. It gets very snowy, the quality is noticeably different. Can't figure out why. All I can assume is its the apps themselves. Cause I tried different cables, I tried plugging it in different tv's. Reset my Apple TV. Almost anything you can think of. And the quality is noticeably different on certain apps compared to others.
