I've had the DVP-NS710H for eighteen months and I'm very pleased with it. Upconverted picture quality over HDMI is excellent and artifacts seen on older DVDs that were prominent on older players are now well hidden.
My only negative comment is that when alternate DTS soundtracks are selected and sent over HDMI all you get is silence. My solution is to use a separate digital audio coaxial connection that goes straight to the receiver bypassing the TV, a necessary connection anyway if you want to play CDs without turning the TV on, so this negative comment is no biggie.
Recently my DVP-NS710H's remote has become unresponsive, sometimes it works, most times it doesn't, I've tried changing the batteries that did no good. The problem is I'm not sure if its the remote or the sensor on the front panel of DVD player that is at fault. I noticed a couple of recent reviews at Amazon have mentioned the same problem. Does anyone know a solution to this problem?
