Glad to have you drop by. But just so you know, this forum is meant to mainly support US products and customers. And from what I can tell, this model is for Australia. (Correct me if I'm wrong.) Generally, I'd refer you to the country code support portal for Samsung, because I support US products as I mentioned. Regardless, I researched your question, and here's what YouTube says: http://support.google.com/youtube/bin/answer.py?hl=en&answer=78358

May I know what is the minimum internet download speed required to view youtube on samsung smarttv without stutter? My tv is UA40d6600. It has a built in wifi, which I connected to my router without a problem. My internet download speed is 1mb/s. Everytime I open a youtube video, it loads and stops every few seconds. It isn't a good experience at all. To view a smooth video, I have to pause the video and wait until it loads to finish, and the loading takes ages too! Appreciate if someone can inform me the minimum download speed required to view youtube on samsung smarttv without stutter. Thank you in advance
