The log also seems to imply that you had a missed recording that was started at boot time.
That's this bit:
This would seem to be correct as the Grand Prix qualifying filename indicates a 09:15 start, but it's actually 09:32 when it gets there.[/Q
I think the scheduling was changed for the highlights on CH4 due to rain delays at the circuit.
F1 Qualifying was moved and the box picked up the change and recorded it at 07:55 this morning.
Does all that point to the issue?
UPDATE: I've rescanned now and have two additional bouquets, All Channels and Last Scanned. I also have a zap timer coming up this morning so, fingers, crossed, all may be well?
