Need more than 6 tuners

My service comes with a DVR. I also pay for a 2nd DVR and Premium DVR service.    When the cloud DVR service cam about, I noticed that my tuner count went from 12 to 6.   Well, my household increased with 2 more adults, and 80 year old dad has sent the last two years juggling the recordings to keep the family happy.  Well, we are starting silly season again with College Football, Pro Football, ad Pro Hockey as well as the normal show schedules.   I am tired of this.  How do we fix it without throwing someone out of the house?
