Without a doubt, NextPVR is the absolute BEST replacement for Windows Media Center which I thought I would never be able to give up. This configuration has saved me a bundle in monthly cable company fees. It has slots for 2 cable cards which I picked up from my local cable company's office for $2/ month fee. The DCR-2650 is one of the most cost effective ways to replace either internal PCI tuners or external HDHomeRun boxes. BTW, don't worry about Hauppauge's docs that say that the 2650 only works Windows 7 Media Center. I now stream a single decoded TV stream from the DCR-2650 with NextPVR to Amazon Firesticks on all TV's throughout the house using Kodi on each Firestick. In fact, I have been able to return all my costly mini TV tuners that I was renting from the cable company for my 'extra' TVs throughout the house. Also getting it going is a little tricky, but there is a great forum and I have fully documented the installation process with Win 10 and my Hauppauge DCR-2650 tuner.

You have to be patient with getting it to work but it is simple to use and integrates beautifully with Kodi.

The program is currently undergoing a major update (to V5) but that is still in development and V4 is what I use with Win 10. I was recently in the same situation as you after I upgraded to Windows 10 and lost my forever favorite program, Windows Media Center (WMC) which worked so well as a reliable DVR with my tuners.
