I own an Astrometa DVB-T2 stick like this and moving
/dev/dvb/adapter0/frontend1 to /dev/dvb/adapter0/frontend0 makes my vdr
2.3.8 (arch linux) running. But I do not succeed scanning for channels here
in Bremen in Germany without errors (I have a nice signal with my antenna
under the roof). With w_scan version 20170107 I get only six lines:

There is no EPG with this. I have tried to use dvbv5-scan like Marko
described but I cannot find initial files for my location.
