Not sure about w_scan, I have scan. It doesn't generate a channel list.
I calculated the following replacement for the uk-CrystalPalace file:
# UK, Crystal Palace
#
# Manually calculated by RLW 2012-04-21T10:20+01:00
#
# T freq bw fec_hi fec_lo mod transmission-mode guard-interval
hierarchy
#
# BBC A — 23
T 490000000 8MHz 2/3 NONE QAM64 2k 1/32 NONE
# D3&4 — 26
T 514000000 8MHz 2/3 NONE QAM64 2k 1/32 NONE
# BBC B — 30-
T 545833000 8MHz 2/3 NONE QAM256 2k 1/32 NONE
# SDN — 25
T 506000000 8MHz 3/4 NONE QAM64 2k 1/32 NONE
# Arqiva A — 22
T 482000000 8MHz 3/4 NONE QAM64 2k 1/32 NONE
# Arqiva B — 28-
# ITV4
T 529833000 8MHz 3/4 NONE QAM64 2k 1/32 NONE
The BBC A, D3&4, SDN, Arqiva A, and Arqiva B frequencies all work fine
with vlc, I get all the channels on the multiplex. BBC B seems to fail
but I have a suspicion that may be that the TerraTec USB unit I have
does not handle HD. I am not sure what the NONE entries are, and I am
not sure if the 1/32 is correct. All other entries come straight from
the OfCom document -- which I assume is definitive.
Running scan I get:
