Hello everyone.

I am running the latest OpenElec on a Raspi 2 (recently migrated from OSMC) and I have been having trouble with MKV playback for a couple of weeks now. The full setup is:

a Raspi 1 Model B+ as a NAS (SMB and NFS) server, two hard drives attached to it and the Kodi Krypton 17.3 Raspi 2 as a player, connected to my Panasonic VT50 TV.

The problem is that most dark areas of the video is hard-pixelated, almost as if it were on SD and it is especially visible between different brightness sections of these dark areas, eg fabric, clothes in general etc etc

The thing is that when I attach the HDD containing the files to the VT50 and use the TV's media player, everything seems absolutely fine. So it's not a matter of the source video file, or a corruption of some kind.

The MKV files are usually 1080p (some are 720p) L4 profile and I have bought the VC1 and MPEG2 codecs from the foundation, which I've put in the /flash/config.txt file.

I am not very certain about the next thing I'm writing, but it's pretty possible this thing started longer than 2 weeks ago, when I was still running OSMC on my Raspi2, but quite possibly not in this scale.

I've searched this forum and others, tried different HDMI cables, different power cables, switched on and off the two hardware acceleration settings on the Player Settings menu, nothing seems to fix it.

The test file I've been using lately gives this media info:

Does anyone have an idea on what I need to do? Thank you all in advance!
