Hi

not sure if im posting in the right place, but here goes.

i have a plex docker installed and running however when i try scan my usb tv card i get the following errors.

May 02, 2020 16:20:31.187 [0x1468e1ce2700] WARN - [E] dvb\_channel\_scanner\_t::do\_scan\_attempt. Tune failed for 816500,7

May 02, 2020 16:20:31.252 [0x1468e1ae1700] WARN - [W] CV4lTunersStreamSrc::Start. pthread\_setschedparam failed 1

if i install TVH plugin it works fine. so im not sure if its a permissions problem, a plex problem (the tuner works fine with plex in windows) or a docker problem.

any help would be great

im in Australia and know ill have to use XMLTV gor guid data (had it set up on windows)

thanks
