You pointed me to the real problem. The tuning didn't work out. dvbscan 
had a wrong initial-tuning-data-file and after writing one manually, 
dvbscan wrote wrong pids to my channels.conf.

Just for the archive: A working initial-tuning-data-file as of 08-12-15 
for de-Berlin is

T 177500000 7MHz 3/4 NONE QAM16 8k 1/8 NONE
T 191500000 7MHz 2/3 NONE QAM16 8k 1/8 NONE
T 506000000 8MHz 2/3 NONE QAM16 8k 1/8 NONE
T 522000000 8MHz 2/3 NONE QAM16 8k 1/8 NONE
T 570000000 8MHz 2/3 NONE QAM16 8k 1/4 NONE
T 658000000 8MHz 2/3 NONE QAM16 8k 1/8 NONE
T 754000000 8MHz 2/3 NONE QAM16 8k 1/8 NONE
T 778000000 8MHz 2/3 NONE QAM16 8k 1/8 NONE

and the three flaky lines in my channels.conf should be
MDR 
Sachsen:191500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_3_4:FEC_1_2:QAM_16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:101:102:1
arte:191500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_2_3:FEC_1_2:QAM_16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:201:202:2
NDR 
FERNSEHEN:191500000:INVERSION_AUTO:BANDWIDTH_7_MHZ:FEC_2_3:FEC_1_2:QAM_16:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_8:HIERARCHY_NONE:301:302:3

Thank you, Nico.
