I've been trying to use a Freecom DVB-T USB stick.

With the latest data for the UK Winter Hill transmitter (taking account
of the switchover in December 2009), it works except for the BBC
channels:

>>> tune to:
>>> 801833000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_32:HIERARCHY_NONE
WARNING: >>> tuning failed!!!

This is with the following tuning information:

# UK, Winter Hill
# Populated by J. Hornsby from a scan of active multiplexes
# UK, Winter Hill B Ceased broadcasting on 02 December 2009
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval hierarchy

T 801833000 8MHz 2/3 NONE QAM64 8k 1/32 NONE

I would appreciate any suggestions.
