The bit map for programming the modulator is all over the place.
Map shown below for the video modulator.

Code:

  Video_C1.7 = 1
  Video_C1.6 = 0
  Video_C1.5 = SO
  Video_C1.4 = LOP
  Video_C1.3 = PS
  Video_C1.2 = X3
  Video_C1.1 = X2
  Video_C1.0 = SYSL

  Video_C0.7 = PWC
  Video_C0.6 = OSC
  Video_C0.5 = ATT
  Video_C0.4 = SFD1
  Video_C0.3 = SFD0
  Video_C0.2 = SREF
  Video_C0.1 = X5
  Video_C0.0 = X4

  Video_FM.7 = 0
  Video_FM.6 = TPEN
  Video_FM.5 = N11
  Video_FM.4 = N10
  Video_FM.3 = N9
  Video_FM.2 = N8
  Video_FM.1 = N7
  Video_FM.0 = N6

  Video_FL.7 = N5
  Video_FL.6 = N4
  Video_FL.5 = N3
  Video_FL.4 = N2
  Video_FL.3 = N1
  Video_FL.2 = N0
  Video_FL.1 = X1
  Video_FL.0 = X0

Hopefully when I get finished anyone needing to setup a channel will not realise that.

What I am working towards is having a number of presets. Each preset will have associated with it a standard and also a channel.

Instead of selecting a channel number from a set number of channels the channel required will need to be setup by selecting a number of options. Such as Frequency, negative/positive video, AM/FM sound, sound separation,  etc.
The options will be easily selected using the LCD and rotary encoders. The microcontroller will take care of changing the options into the gobbledygook needed to program the modulators.
This will release most of the capability's of the modulator to the user rather been stuck with a limited amount of preset channels. On each preset the standard converter can be switched off so it can be used as a modulator only.

At least that is the plan.
