Hi Hope someone cam help? My x8 has issue with playback of 1080p files, mainly sports. A small number of 1080p files play Okay but the majority are virtually unwatchable. 4k plays fine with no issues at all. I have reset the box and this helps for a few days, however, after a while it goes back to normal again. I have tried a different HDD and streamed it from PC but it’s still the same. It’s as if it’s playing at 10 frames per second. There are spells when the files run smoothly but after a while it goes back the stuttering again. I am running the latest firmware. Any ideas?
