I have not managed to play videos by usb port but the music goes on.
There are too few parameters stored in the "scenes". for example between the input and the input of TV tv / box decoder, the offset of the sound with the picture is not the same therefore obliged to re-set every time.
If the functions are well, the handling is easy and the amp seems solid. It is also quite imposing, well before check-dimensional (leave room on one side and above for cooling.)
