Yes, this is an old topic, but I bought a BD-E 8300?? and have no success to find some channels on TV

I got access by FaNet Method and see the following settings:
Region: Pannordig
Model: 8300N/XE
Tuner: SEC_T2_2
Someone an idea what I have to change for german TV support?
I have a second BD-Player BD-E 8500, that works fine:
Settings are the folowing:
Region: Paneuro
Model: 8500/ZF
Tuner: SEC_TC
But if I change the 8300 to Paneuro, 8300/ZF and SEC_TC, it won't work and find no channels!
PLEASE Help!
