Nvidia Shield TV dvb-t/t2 tuner

[pre]

Has anyone run a USB dvb-t/t2 tuner directly through the Live Channels Android TV app on an Nvidia Shield TV or does it need to be run through Plex? A brief google throws up a lot of lack of google support of dualHD tuners.

Was not really a Plex question - was more about the native Android TV Live Channels app. Seems to have US TV format support but nothing clear about whether or not it works with the EU TV standards nevermind if it has EPG or anything.
