DirectTV and Kodi

I’ve spent quite a bit of time looking in the forums and google to get an answer to my issue. Today I use Windows Media Center and have a Hauppauge PVR tuner. By tuner I don’t use over the air, I have DirectTV hooked up to the composite HD and use the MCE IR blaster to change channels on the DirectTV receiver. I understand that Kodi works very will with NEXTPVR for over the air stuff and streaming content from the internet. I can’t see a simple answer to using Kodi in the same manner that I use Windows Media center with DirectTV. Does anyone have any thoughts on this?
