There are a few shows that I record weekly and after they are in the Now Playing list I set the keep until option to keep them in the Now Playing list for 7 days but I have been running into a problem lately.When I make this change a conflict comes on the screen and says it is going to delete shows[not always the same ones ]early.So nothing has been deleted before I have had a chance to watch.At least not lately but it has happened in the past .Why is it just these shows .Is there anything I can do to stop it from continuing to happen.Thanks in advance for the help.
