Just wanted to throw this out there to those who are interested. This plugin allows you to stream live TV from NextPVR - it's based on some of the code psyciknz wrote for NextPVR-Plex but mine only streams live TV. plex-npvr can handle subchannels (4.1,4.2, etc...) and the ability to have broadcaster logos displayed on the channel listing.
See GitHub for more info:

Didn't mean that as a question :)
