Hey. Some more observations about 818 behavior. I thought initially that the the network applications such as vTuner and DLNA controller are slow, but it seems it is OSD that is slow. If I look to the device screen it reacts instantly (within 0.1 sec) to the remote, but OSD reacts only about a second later after that, even slower when the page changes. Incredible. They have 4K up-scaling (useless because it appears it does't even able to passthroug 4K because of HDMI inputs are not capable of it) real time, but unable to update the OSD within 0.1 second time - quite normal response time expected from any UI to be usable. I haven't seen this on any other non-Onkyo devices, even on very old DVD and even older VideoCD players. How come no single review even mentioned this... It is really ridiculous that in 2012 this is considered normal and no one even bothers to mention this as a problem! Or is it only me who have such a slow OSD?
