Every time I try to DVR a CBS show, it will only record 5-10 minutes and then end even though the setting is to start 1 minute early and end 3 minutes late. DVR is only 30% full. I don't have this problem with any other network. Most recently occurred with Criminal Minds from last night (1/31/18). It recorded 4 miknutes and quit. Anyone else having this problem with CBS? Could this be their way or forcing people to pay for their CBS All Access app? I have tried resettig the box but that doesn't help.
