Well, better late than never to reply!
I did indeed end up looking up mux frequencies directly and guessing at
a few of the other parameters and hey presto it started working.
For the archives, here's my initial tuning file:
# Malvern, Midlands
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
T 714166670 8MHz 3/4 NONE QAM16 2k 1/32 NONE
T 658166670 8MHz 2/3 NONE QAM64 2k 1/32 NONE
T 634166670 8MHz 3/4 NONE QAM16 2k 1/32 NONE
