Hi! If this is the right place, I can as well try to describe it now. (And I hope I makes sense.) The bug is about the "Enable/Disable signal detection". As it is now in videoinput.c: int videoinput_check_for_signal( videoinput_t *vidin, int check_freq_present ) { if( videoinput_freq_present( vidin ) || !check_freq_present ) { switch( vidin->cur_tuner_state ) { case TUNER_STATE_NO_SIGNAL: Should be: int videoinput_check_for_signal( videoinput_t *vidin, int check_freq_present ) { if( !check_freq_present || videoinput_freq_present( vidin )) { switch( vidin->cur_tuner_state ) { case TUNER_STATE_NO_SIGNAL: So just switch place for "videoinput_freq_present( vidin )" and "!check_freq_present" so it actually cares if you disable signal detection. With this change, disabling signal detection will remove the frame drops I have in tvtime. Cheers, have a nice weekend.
