Since Thursday, every series recording is being recorded twice. This happened before on the odd recording, but when it did the second recording was a minor nuisance and only used a single tuner. Now, it is using both tuners for a single (duplicated) recording, meaning that you can't watch live TV or record another program at the same time.
This has been the case for around half dozen series from Thursday to Sunday; every single series recording. On Friday I power cycled the box and deleted and re-configured all the series recordings, but still it wanted to duplicate them.
I just spent 10 minutes deleting all 39 of my series recordings (that is a painful process) and am now working on setting them all back up. I power-cycled after deleting them so hopefully it is starting with a clean slate. This is maddening.
