It's well known that Smart TVs, players and PCs do not play the same or all content. That is a fact and well discussed so I defer to priors.
To fix this you would have to convince Samsung there is a product defect (good luck) and they need to issue new firmware.
My fix would be to go with what works. Smart TVs are pretty dumb.
I have a older samsung tv (ue32es6100) and for years i am using the same usb hard drives (toshiba 1 &1,5 TB). I am having 3 of those drives with movies/series on it (all mkv format). And everything played well on all 3 drives for years.
Now suddenly when i want to watch something on my samsung tv after a second of 30-45 he skips stops the file and go load the next file and start playing this one. After 30-45 second it happend again and it plays the next one. Sometimes the disk (and tv) freezes and i have to unplug the samsung tv. Even movies or series that i already watch with no problem in the past but still are on these 3 usb disks now all have this skip problem!
All three disk still work on my samsung tv in the living room (newer model) and they work on my computer as well on my usb port of my blu-ray player so normaly the disks should not be the problem.
It also can not be the firmware i guess because since it is an old model the latest update was from more than one year ago. I am a bit stucked what to do next and how to solve it. Normally i would say it has to do with updates, but with an old tv there is not much happening for updates. The disks seem to work perfect on other devices.
What i did so far without change:
- try all 3 usb ports on tv (including the higher power port)
- all updates are there. Last update is from last year summer by the way.
- factory reset 2x (one thru menu option + one thru service menu)
- factory reset of smart hub.
- connect the usb drives to a usb hub with extra power and than to the tv.
- copy some older movies that worked before well to a usb stick (no drive) and still skipping problems.
- deplug the power cord of the samsung tv for 12 hours
- deplug the internet cable, coax while turning on tv and playing from usb.
- checked all 3 external drive on faults on my PC (chkdsk etc.) but nothing to be found.
- all 3 disks work without problem on other devices than my old samsung
Anybody an idea where to search now?
