4K playback issues on new Windows 11 PC

[nabelnabel]

Hi all, I just recently got myself a pretty powerful new PC and had been looking forward to using it to watch some 4k HDR video files I have downloaded. It has a Ryzen 7 9800X3D, Nvidia 5070ti, and 32gb of RAM.

I've tried a couple of different files so far and they both work fine for about ten minutes (sometimes more, sometimes less) before playback stops - the image freezes and the audio stops, although the timeline / scrubber bar at the bottom says the movie is continuing to play.

I've tried a number of different media players - VLC, PotPlayer, and SMPlayer. I have tried two different displays and a couple of different cables as well - my 4K HDR tv and my 1440 HDR PC monitor. I have tweaked numerous settings including enabling and disabling hardware acceleration, turning HDR on and off, watching SDR files, changing the file cache amounts, trying different codecs, etc. I'm feeling pretty stuck and of course the most annoying thing about this is that because the video files play just fine for a decent amount of time, it's just taking a ton of time to troubleshoot waiting for the playback to fail.

For what it's worth I can play recent and fairly demanding games with no issues whatsoever, so I don't believe there is any sort of hardware issue. 1080p files play with no issues.

Any help would be much appreciated. Thanks.

Load a 4k video into one of the players and pause it and then drag it past the point of freezing,if it stops scanning after 10 minutes then its bad files.
