Many thanks to David and Darren for your replies,

Yes, the problem was the initial tuning file. It was from the Ubuntu 
Feisty dvb-utils package. Running w_scan allowed me to get a file that 
works with MythTV, but tzap was not happy with the "AUTO" parameters it 
produced. Using David Matthews information, and the frequencies found by 
w_scan (and verified on www.ukfree.tv) I could make a channels.conf file 
that kept tzap happy.

For the record, here's my initial tuning file for Craigkelly:

# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy
#MuxA 23
T 490000000 8MHz 2/3 NONE QAM64 2k 1/32 NONE
#MuxB 26
T 514000000 8MHz 2/3 NONE QAM16 2k 1/32 NONE
#Mux2 29
T 538000000 8MHz 2/3 NONE QAM64 2k 1/32 NONE
#Mux1 33
T 570000000 8MHz 2/3 NONE QAM16 2k 1/32 NONE
#MuxD 39
T 618000000 8MHz 2/3 NONE QAM16 2k 1/32 NONE
#MuxC 42
T 642000000 8MHz 2/3 NONE QAM16 2k 1/32 NONE

# The following were added by w_scan, but no channels found by scan
#30
#T 546000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
#34
#T 578000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
#47
#T 682000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
#56
#T 754000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
#59
#T 778000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO
#62
#T 802000000 8MHz AUTO AUTO AUTO AUTO AUTO AUTO

I dont know why there are other frequencies present, but no channels 
were found. The scan program found some duplicate channels on 
frequencies off those listed above (eg 490166670). I'm not sure why 
again, but I removed these from the resulting channel list.

So, thanks once again.

Dave
