DVR - recording at the wrong time
I have a series recording set for the NBC Nightly News. In the last couple of months it has on ocasion, including tonight, recorded at the wrong time, 5:00P instead of 5:30P. I have checked the onscreen guide on the nights where this has happened and the guide has been correct showing a 5:30 - 6:00 time.
Please investigate why this is happening and correct it.
