I just got my NP-1 yesterday as well. Unfortunately i only have a 1080p TV, so no 4k review for you guys today. My internet is also 100/5mbit. My source content was, Streaming services such as netflix and the 4k streamer. Cloud applications, such as Bitcasa, and local media from my NAS in various forms of .ISO and h264 encodes.
Hardware is Samsung UN55B8500 and a Pionner elite VSX-53
First off, yes the Air mouse does take a little bit to get use to. However i can not imagine trying to use this interface without one. It does save a lot of time when entering information. A blue tooth keyboard is a great suggestion.
1. Video Quality.
They have four media players on this box. ES file, MX video, XBMC and one other one.
So far all of the video's that i have thrown at it have looked pretty good. I tried a .ISO bluray of the avengers which played (Through XBMC, but not the others) and looked great. I also tested a few other .MKV/H264 encodes i had to see how they looked and they all looked great through all of the media players. I tested several of the streaming services which also looked good. Netflix, the 4k streaming one that they had.
I also saw that the ES File player had a cloud option, which i was able to link my bitcasa account. I was able to also stream a 1080p/DTS audio (about 16gb file) from the cloud to the player without issue. I did run into some issues with the persistancy of the cloud connection. When i left my bitcasca folder and went off to do other things and came back to it an hour later it still had cached info from what it looked like, but it wasn't able to access anything. A close and reopen of the app worked fine.
XBMC is slick. I did have an issue of playback of American Ninja warrior's. For whatever reason they where incredibly choppy. They played fine on the stock media players.
I've been having audio issues through XBMC. It won't detect that i have a DTS capable receiver, so it only sends 2 channel PCM and if I try to pass-through i get loud static. I opened a case to see if i can get this fixed some how. DTS Audio passes through fine through the other media players. [http://forum.xbmc.org/showthread.php...21#pid1757121]
so we will see.
I haven't been able to test DTS-HD audio yet, because my reference audio is in the .ISO format, which the native media player doesn't support.
I also had issues with the power button turning it off. And then when i tried to turn it back on i got a blank screen so i had to hard reboot it.
I didn't see a Plex app that was "supported" for this, so i don't know how i can get that on there. I'll have to look into it a bit more tonight.
The UI feels just like an android tablet. So it's def has a lot of things going for it, it just needs some more polish, and obviously to fix the audio pass-through issue
