I just bought the 55" M series (I'm in Mass. not Canada). There is a V (menu) button that takes you to the apps. Ultraflix is not on the selected apps when it first opens, but when you go to the Yahoo App store, it is the FIRST one to choose. It also stands out because it has a blue sash that highlights "All 4K Content". You can easily add it to your favorites which will put it on the preferred menu when you press the menu button. Very exciting! Nice discount TV, but I am going to return it and get the 65" because the 4K can really be appreciated on the bigger sets. When Sony starts offering UF, I am going to buy that one too. I love 4K. Once you get used to the clarity, watching anything else is like going back to SD on the old Zenith.
