I've never had playback problems and it was almost 80% capacity of the internal hard disk and now the audio and video is cut in the playback. I have put another disk via usb and it reads perfect. It can be the internal disk that is damaged ?. Now I have it analyzing with windows, in case that is faulty which you recommend me to buy.
Currently I have a WD Green disk of 3tb, sata 3 -3,5" ,the hard drive has about 5 years.Thanks a lot.
