I have got a DN2820 with 4 GB ram and 120 GB SSD running Windows 8.1 + XBMC Gotham and it works perfect, but when I try to play a 1080p mkv in VLC the movie is stuttering and the cpu usage goes to 50-60% (1 core 100%?) - seems like VLC is not using the gfx-hardware and tries to play the movie with software rendering?! Anyone who can help me set up VLC and Youtube (same problem with 1080 content) to use gfx hardware instead of software? I have checked the option: "Accelerated video output (Overlay)" in VLC.
