Now to view this a is bit tricky. Close the advert on the screen, you might have to try this several times. Close the popups it opens, then select the play button. The advert will still show on the screen, but when you go to full screen, the advert is gone. I had no other problems, except it was slow loading at first, but played fine. Pause it and let it buffer if you encounter a problem.
These 3rd party sites, which are not Hulu, Netflicks or some reputable streaming site can be tricky to maneuver and often bug ridden, but we encountered no issues.
