How to get Fritzbox SD private channels in plex

Server Version#: Version 1.41.5.9522
Player Version#:
Tuner Make/Model: Fritzbox 6590 cable
Guide/Lineup name:
Using XMLTV?: no
Channel number/Name: RTL, Sat1,… (SD not HD)

on my Fritzbox 6590 cable that is connected to german Vodafone cable internet I can see the german public channels like ARD in HD , also in PLEX. However I can also see private channels like RTL and SAT1 in SD on the fritz.tv app but there is not a single SD channel in plex when i add the 6590cable as a tuner. Regardless which of the EPG providers I try. I only see the hd channels with a “secured” label and cannot access them.

what can i do to get them into plex ?

kind regards
chris

Those are most likely encrypted/protected, requiring something like a HDplus subscription. Plex DVR/Live TV doesn’t support encrypted channels.
