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
transmission_mode: 8
guard_interval: 1/32
hierarchy: n
transportid: 24640
Still, if it 'ain't broke...
