I like to use the Sony stock video app to view 4k content as it purely uses the TV hardware (I believe).

However, some 4k videos or even 1080p and lower videos have issues whilst playback.

For example the video will pause after about 40mins on a 4k file a full reboot fixes this issue but annoying it's happening, playback is via USB.

Also on lower than 4k the audio will be crackling/pausing, no idea on how to fix this. As the TVs hardware should be able to play back 5.1 audio..some videos work fine some don't.

When I play all files in nova player it's fine z but it seems when the stock video app works it brings out the best picture and audio from the TV.

Any way to change settings for play back to avoid issues stated above within the stock video app that I can do z as I can't see or change any settings that I'm aware of?
