Hello people,

i bought this tv on black friday so it's new.

But when i was trying to watch Witcher 4K HDR from a usb 3.0 external hdd (i had to download because my internet connection is 6mbps, otherwise i have netflix account. ) i had playback problems such as stutter/freeze/image corruption etc.

The images was getting corrupted/blocky and A/V was stuttering and freezing. I thought maybe TV was just not powerful enough to play this but for a new TV it was unlikely.

Then i realized stutters were happening when there was talking, and i saw there was more than 25 subtitles in the movie file including weird ones (chinese etc.)

Even though i disable subtitles or choose a subtitle from the enormous subtitle list, the playback stutters when movie encounters a subtitle.

So i removed the subtitles except English and Turkish from the file to try it out and now movie playbacks nicely. When you have a small list of subtitles there is no problems.

I'm not sure if the number of subtitles or weird subtitles creates this problem, even tough disabling subtitles doesn't resolve the problem unless you remove the subs from the file itself. (MKV container)

Samsung engineers might pinpoint to problem and fix.

Thanks for reading.

You sir are a genius for figuring out that the subtitles were an issue and finding a workaround. 

Thanx for posting, it worked for me.

Just adding another comment confirming it's the subtitles.
