Synology DS716+ and TVButler. PLEX doesn't find any chanels

Hi

Just installed TVButler-Stick on my Synolgy. On a fist tray all chanels of our cable provider have been found. Only the EPG was not available for all of the chanels. So i removed the configuration and tried to install a second time. Now PLEX can’t find any chanel at all. But DVBLink-Server does. In DBVLink Server i have the possibilty to configer stuff like frequenzy, symbolrate, network-ID and more. That seems to be very helpfull bevore scanning.
Can i configure that stuff in PLEX to? Where?
