More than 4 hours of tv program data?

I have an HDHomeRun Connect and it works ok for channels. I also have pledged for the DVR component and that works good. However, I am a big football fan and want to record games that are more than 4 hours in advance. The EPG (Electronic Program Guide) in the HDHomeRun has only 4 hours of data. I would like to record a game that is on the air tomorrow at noon. I can not do that at this time.

How do I get (buy if necessary) EPG data for more than 4 hours?

Kodi running on a Raspberry Pi 2 via OSMC
HdHomeRun Connect
NAS is My Cloud 4 TB (for recording the shows)

Thank You,

Mike
