netflix streaming question

Netflix streaming is being super laggy for me-- meaning the audio plays fine but the picture gets stuck. The buffer is good and reloading doesn't help. It used to just do this for the first few minutes or the last few minutes of a show but now it is doing it all the time. Playing in either Chrome or Firefox makes no difference.

With my recent all-the-time headaches, TV is about all I can handle. Anyone know how to fix this?
