Are the shows having to reload, or are the rebuffering? Only reason I ask is if is constantly having to buffer that usually indicates a network performance issue. If you're using wireless I'd try wired to test if the buffering goes away. If it does you've got your answer, and can try troubleshooting the wireless. If you still have problems with a wired connection, then I'd run an Internet speed test to see if something is going on with your Internet connection.
