Recording play back stuck at double speed

I've started having an issue with some recorded content suddenly running at like double speed. No buttons were touched to cause it. Hitting the back button stops it and then hitting play again is fine. Anyone else seen this?

Shield Pro 2019 with latest update. Channels Android TV latest stable release, Channels DVR on Qnap, v2021.03.16.1916

What are the recordings? TVE or OTA? HD pr SD?

"latest update" and "latest stable release" is not a valid or useful version numbers and can mean anything at anytime.

I would suggest you update to the latest beta app on the Shield and see if the behavior happens then.

You also could try changing to software decoding in the app.

Also, can you playback the files on you PC using VLC just fine?
