As a substitute for a Kenwood DVR-6100 5.1 Heimkinoanage. I miss nothing - on the contrary, had to get next to DVD also Blue-ray and WiFi. Construction and installation were problems. Functions are obvious and sound is good. Makes its service without complaint. As Dipl. Ing. With moderate claim I am very pleased to have this device on the side of my Samsung LCD TV LE26B350. I would recommend it without reservation.
