The program works very systimatisch and is active with many calculations. The program is a good program to play most video formats, but not all. Buyer gabs no accurate playback formats of video files. but to Bluray's play he is sufficient. The function as the Windows Media Player by clicking to get through the menu is replaced with a virtual remote control and thus more difficult or annoying to use. Shipping was very fast and am satisfied no Beschödigung the DVD and the packaging.
