"Protected" Channels show up fine in other software

Why is it that plex shows most of my channels as “protected” (70 of them) but in WinTV and NextPVR then show up and play just fine?

I have 74 channels that work great in WinTV and NextPVR, but plex shows them as protected and only 4 work. I have a WinTV-quadHD card/

Also the channels show up as clear QAM in WinTv

I have notice this issue as well and am looking for a solution.

Still no resolution in the latest version.
