This is unexpected && should be fixed to fit to w_scan's default behaviour: first QAM_64, then QAM_256.

Can you pls re-check with the following change in countries.c line 500ff

/*
 * start/stop values for dvbc qam loop
 * 0 == QAM_64, 1 == QAM_256, 2 == QAM_128
 */
int dvbc_qam_max(int channel, int channellist) {
switch(channellist) {
       case DVBC_FI:    return 2; //QAM128
+      case DVBC_BR:
       case DVBC_FR:
       case DVBC_QAM:   return 1; //QAM256
       default:         return 0; //no qam loop
       }
}

    
int dvbc_qam_min(int channel, int channellist) {
switch(channellist) {
       case DVBC_FI:
+      case DVBC_BR:
       case DVBC_FR:
       case DVBC_QAM:   return 0; //QAM64
       default:         return 0; //no qam loop
       }
}

I don't think that adding QAM_128 makes sense. Later, if i have more reports from 6MHz network users, i will reduce the number of symbol rates.
