I am very pleased with the new CyberLink PowerDVD 15 software could be installed easily and does what it should. I have used so far PowerDVD 11 and now have "upgraded" to version 15. At this version here I particularly like the very clear and uncluttered user interface and the speed of the program (by which I mean the virtually non-existent load times and lag-free response to inputs). The "Basics" remain good, all popular formats to play, media usage across multiple devices such as smartphones and tablets are integrated, picture and sound quality are very good and the existing in previous versions gimmicks like the Smartphone remote control app are still present. With me on the computer running Windows 7 DVDs, Blu-rays and 3D movies are played back with me without any lag in fabulously good quality. Even with my homemade works copes software. This is Allerding s just simple DVDs. All my Blu-ray, purchased or presented itself, whether as a 2D or 3D, run without problems in the best quality. There was no disc that has not been recognized. I would recommend the program in any case, 5 stars!
