Hi folks,

so here some more debug information:

using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0'
initial transponder 198500000 1 3 9 1 1 3 0

Done.

Under Windows everything works fine (with firmware 5.5.21.0 from dnt). 
No errors in the log file. So I'm wondering why there should be any 
problem with the stick itself.
