Those files (dvb-t/uk-{regions}) are not in the dvb-apps hg repo, so I don't know where they came from, but considered that they don't work for me at all (and w_scan does find some), their contents are either wrong or outdated.
The fedora package changelog possibly says tuning files are kept elsewhere and were last updated over 2 years ago - I know it is probably cliche to assume every *.fi person knows every other *.fi person, but do you? :-)

With a full scan taking 8 minutes (and quick "assisted" scan based on presets not working at all), channel-scanning can't really be modularized and built into an application. Actually even w_scan needs assistance about which *country*.
Also a typical user might like to try a few different applications. I use mplayer-derivatives - mplayer, gmplayer, gnome-mplayer, dragonplayer - mostly because of its widest/earliest codec support, but I am not against using another if it offers more DVB-centric user-interface. I really think w_scan should by default write all variants of channels.conf formats, or a master-form convertable to others, just to save the 8 minutes of re-scan. (being able to convert quickly, or for application to standardize would be nice, but seeing as the formats have different info, that idea does not seem likely).
