Hello list, after entering the command ./szap -c channels.conf-dvbs-astra n24 -r I got the debug output : Apr 5 23:04:13 darkstar1 kernel: DVB: registering new adapter (TwinhanDTV StarBox DVB-S USB2.0 (VP7021)). Apr 5 23:04:13 darkstar1 kernel: DVB: registering frontend 0 (Twinhan DST-like frontend (VP7021/VP7020) DVB-S)... [...] Apr 5 23:05:34 darkstar1 kernel: vp702x_fe_set_tone Apr 5 23:05:35 darkstar1 kernel: set_tone cmd succeeded. Apr 5 23:05:35 darkstar1 kernel: vp702x_fe_set_voltage Apr 5 23:05:35 darkstar1 kernel: set_voltage cmd succeeded.

Apr 5 23:05:35 darkstar1 kernel: vp702x_fe_get_tune_settings Apr 5 23:05:35 darkstar1 kernel: setting frontend to: 1880000 -> 1880 (758) LNB-based GHz, symbolrate: 27500000 -> 327680 (50000) Apr 5 23:05:36 darkstar1 kernel: tuning failed.

Thanks in advance and of course feel free to ask for more debugging information. see you Uli _______________________________________________ linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
