Actually no... you need to ignore the comments in the file. Without NICAMSTEREOMODE set it uses 0x00200003 which selects Zweiton analogue stereo - which results in mono in New Zealand. If you want it set to automatically detect then you need to use 0x00200001. This will recognise the format and switch to it within 0.5 seconds.
I however prefer to force it to Nicam using 0x00200008, as all our channels use Nicam. If you wish to test this for yourself then you can use the following:
Code:
# iicset4 0x88 0x10 0x00200001
# iicset4 0x88 0x10 0x00200003
# iicset4 0x88 0x10 0x00200008
You will notice that the first and the last will sound the same, but the second line will switch your whole system into mono (it may also increase in volume slightly).

The UK TiVo (v2.5.5) uses Channel/Number setting for the UHF Channel frequency and ignores the Station/FccChannelNum. When I use the numbers on the remote, it tunes directly to that UHF frequency - there does not seem to be any translation or mapping happening.
The ChannelMap.itcl plugin alters the Channel/Number field and as such results in setting the UHF channel mapping... so for me (as a programmer) it was just easier to make changes to the ukchan module.
