Here are some tips on how to get the best viewing experience
Watching in HD (High Definition)
The movies are set to display using the highest possible settings to give you a clear and crisp viewing experience. However, this option uses the most bandwidth and if your connection is slow or playing up the movie may stop and start or become jerky. You can reduce the playing size to a lower bandwidth which will improve playability over a slow connection BUT the viewing experience will not be as good. Its a compromise that you sometimes have to make. To alter the settings click on the HD button as shown below and choose another setting.
