OK i finally just bought a Dune HD Max

as expected im having a few problems that i hope someone on here will be kind enough to help me fix

first off, after approx. 15 mins of playing a disc my tv screen goes black and sound mutes for about 2 seconds, the same as if a hdmi refreshes, but the cable is in securely. i have the video display set to auto, no upscaling or anything, as i let my denon receiver do the upscaling

secondly, i bought this to replace my sony bdp s380 player for watching blu rays but the picture just doesnt seem to be as sharp despite me using the exact same hdmi cable. motion is fine but there seems to be aliasing or jittering of some objects at certain times in the centre of the screen


i'm hoping someone can help as i really dont want to have to sell or send this back as its something i have wanted for a very long time. any hints or tips on how to get the best out of this device would be much appreciated
