I managed it to enable some debugging output. "modinfo" is your friend. modinfo [modulename] watch out for "parm:" lines, start the module with the corresponding parameter e.g. modprobe dvb_core frontend_debug=1 In /var/log/messages there a lot of debug messages from dvb_frontend_autotune about a drift... dvb_frontend_autotune: drift:-5500 inversion:0 auto_step:4 auto_sub_step:2 started_auto_step:0 dvb_frontend_add_event dvb_frontend_autotune: drift:-5500 inversion:1 auto_step:4 auto_sub_step:3 started_auto_step:0 dvb_frontend_ioctl dvb_frontend_autotune: drift:6875 inversion:1 auto_step:5 auto_sub_step:0 started_auto_step:0 dvb_frontend_add_event dvb_frontend_autotune: drift:6875 inversion:0 auto_step:5 auto_sub_step:1 started_auto_step:0 Is the tuner not able to catch the signal? What else in the debug messages could be of interest?
