Can you please describe where you see the buffering? I want to check if I also have this.

i tried the "after earth" 4k trailer and there was buffering on it (2 or 3 times)
(size is less than 2GB so pretty low)

i also tried (for test purpose only) the martian in 4k (MKV around 56GB)
during the movie i had buffering (2 times)

how does it appears :
movie stop and info bar appears displaying "buffering XX%"
buffering length was around 5 seconds
movie then resume automatically


i check and it seems that movies with issues are encoded with X264 codec (but in 4K)

those i tried in HVEC X265 doesn't seems to have the issue. maybe something to explore there

I check on the first page and maybe what i'm seeing is what is called "stuttering"


I checked with media info and "after earth" trailer is indicating :
