Must me unfortunately connect the many reviews. Picture and sound are great, but the software is more than poor. Although I do not think that the operation is troublesome. Also bothers me gar nich so much the time to boot up, or delay at the transmitter switch, but that the device simply spins. Often it works flawlessly for days, then it turns off arbitrarily and after a few seconds, or simply out of the standby mode one, which is particularly funny when it happens in the middle of the night. The contact with the support brought so far no solution, all automatic updates, etc. is turned off. Nevertheless gibe no change. The only possibility to exclude certain that the unit is turned on by itself to press the power button. There are so far no satisfactory solution to this problem. Too bad. I can not understand really that Philips is such a thing does. It can not be that hard but to develop a robust software. We can only hope that there are more updates, which resolve these issues and is available at the end of a stable system. Unfortunately, typical "banana product" that the customer only matures.
