Sure - I appreciate that, I'm using the following which I've hand
crafted using the ofcom detail from:
Which is (without the HD multiplex which I can't use):
T 794000000 8MHz 2/3 1/2 QAM64 8k 1/32 NONE
T 738000000 8MHz 2/3 1/2 QAM64 8k 1/32 NONE
T 802167000 8MHz 2/3 1/2 QAM64 8k 1/32 NONE
T 754167000 8MHz 2/3 1/2 QAM64 8k 1/32 NONE
T 842000000 8MHz 3/4 3/4 QAM16 2k 1/32 NONE
There are some differences with yours and so I'll try that tomorrow, but
from my limited understanding I believe that dvbscan just uses it as a
starting point anyway (but I'm happy to be corrected!).

Thanks again - based upon the info you've supplied I'll try some of your
settings and verify the configuration information I have to try and find
the oddity. I'll send an update with my findings ...
