Playback Error on recordings

The only way we watch TV is through the Telus+ TV app. We have an apple box.  And it is when we try to access our recordings, we get "playback error".  We were also having problems like when we fast forwarded a recording, it wouldn't let us rewind and everytime we went to "Guide" it would take us back a day and we would have to scroll through manually to 24 hours later.   I have reset the entire box to factory settings and reloaded the app (as well as reset the modem, logout/in etc.). The fast forward and guide issues seem to be resolved, but we are still getting "playback error" when trying to watch our recordings.
