I am in the Uk and we dont air the episodes as quickly either - I normally go to a site called torrentguy. He has all the episodes virtually minutes after they are aired. You have to upload the episode first - which does take a while but I normally just leave my pc on and go o something else and then when I come back to watch it its crystal clear and doesnt stick at all!!!
Also, if you watch it from here - then try pausing it and then leave it for abou 10 mins cos its just buffering and it needs to catch up with itself - so if you pause it for a while and then come back and watch it - it doesnt stick so much - Hope this helps!!
As Wisteriawoman said, the solution is to open the video and just let it fully load (or at least for a while) before you watch it. That way you won't have to wait for it every minute or so.
