I'm glad you've got it working now. However...

I'm surprised that your parameters for some of the other mplexes differ,
given we're both receiving from the Mendip transmitter:

*************************** 1. row ***************************
         frequency: 738000000
         bandwidth: 8
      hp_code_rate: 2/3
      lp_code_rate: 1/2
        modulation: qam_64
transmission_mode: 8
    guard_interval: 1/32
         hierarchy: n
       transportid: 8204
*************************** 2. row ***************************
         frequency: 754166670
         bandwidth: 8
      hp_code_rate: 3/4
      lp_code_rate: 3/4
        modulation: qam_16
transmission_mode: 2
    guard_interval: 1/32
         hierarchy: n
       transportid: 20480
*************************** 3. row ***************************
         frequency: 794000000
         bandwidth: 8
      hp_code_rate: 2/3
      lp_code_rate: 1/2
        modulation: qam_64
transmission_mode: 8
    guard_interval: 1/32
         hierarchy: n
       transportid: 4161
*************************** 4. row ***************************
         frequency: 802166670
         bandwidth: 8
      hp_code_rate: 2/3
      lp_code_rate: 1/2
        modulation: qam_64
transmission_mode: 2
    guard_interval: 1/32
         hierarchy: n
       transportid: 12290
*************************** 5. row ***************************
         frequency: 842000000
         bandwidth: 8
      hp_code_rate: 2/3
      lp_code_rate: 1/2
        modulation: qam_64

Still, if it 'ain't broke...
