currently running into issues playing a 4k h265 mkv back on a laptop and desktop PC.
all i get in vlc is a black screen and sound (on both laptop and pc) and on the i7 laptop i get stuttering picture in film and videos app on windows 10 (no picture at all with phenom just sound).
weak pc is a phenom 955 and laptop is i7 6700hq both using same programs both 8gb ram.
