I have this problem occasionally with my Tablos.
The settings show that it is set to record various programs every day and when they air, the TV guide suggests that they are indeed being recorded (an example is attached of 60 Minutes from yesterday).
However, when I check recordings, the most recent recordings are from Dec. 10. Nothing new since then despite my daily scheduled recordings.
The auto-delete recordings featured is checked.
Also note that the date of the recordings are frequently out of sequence. Why is that?
