Late to the game here but seriously go with the HDHomerun tuner. Its a little device you put hardwired on your network and connect the OTA antenna. It has two tuners. Then you can use the Plex.tv DVR which integrates seamlessly with the HDHomerun. Plex you can access just about anywhere, cell phone, Kodi, Roku, Smart TV, etc.. There are limitations such as the inability to watch while recording or have automated commercial skip. Additionally the plex listings guide really sucks but you can get the job done, but this would be the easiest way to get done what you want to do. It also removes the hardware dependency of having to install cards.
