I have a problem with picture degradation on recorded TV playback. It appears at non-regular intervals, approximately every minute or so, and lasts for one or two seconds.
It does not happen when watching live TV.
It does not happen on playback, from the start, of a program which is currently recording (delayed playback).
It only occurs when watching a finished recording, and is then actually part of the recording, so I was able to pause playback and grab a screenshot. Playback of recordings made on another PC also exhibits this issue. I tried a rescan, but the problem remains.
Both PCs are running 28.0.105 64bit, Win10.
