Any Linux DVB-T users getting their signal from Crystal Palace might find this page useful:

Linux TV stuff for Freeview from Crystal Palace

I'm in the process of regenerating the channels.conf file.

SDN are transmitting using QAM_64, but stating in the NIT that they're using QPSK :-( Don't know if this is country-wide, or just on Crystal Palace.

See the sections:
Which Freeview channels does the Crystal Palace transmitter broadcast?
How will the Crystal Palace (Greater London, England) transmission frequencies change over time?
