DVR not recording full episode lengths

Hello all, I am new to plex but not to networking and computer management. I have been trying to get my plex dvr fully operational for almost 2.5 months now to no luck. Sometimes it records full episodes but for many it only records 7-10 minutes give or take of an episode. I have checked the logs and cant make heads or tails. I just cant get it to work. Yet it works fine for my movie and other libraries. I have tried countless ways of correcting including software and hardware upgrades but nothing has happened. Before I throw in the towel completely and go a different route I thought I would give you all a try. Thanks
