Hello, Any current vdr doesn't respect valid dvb device frequency ranges. Here on a EPG-Scan it's generate many messages on syslog, like : DVB: adapter 0 frontend 0 frequency 177500000 out of range (470000000..860000000) DVB: adapter 0 frontend 0 frequency 177500000 out of range (470000000..860000000) DVB: adapter 0 frontend 0 frequency 177500000 out of range (470000000..860000000) Any of my three DVB-T devices have different frequency ranges, and the primary device can't receive VHF-channels. frontend 0:0 frequency range 470000000..860000000 frontend 1:0 frequency range 51000000..858000000 frontend 2:0 frequency range 177000000..858000000 Therefore i attach a simple patch to check provided frequency ranges of used dvb-t device driver.
