The old dvb-apps at https://linuxtv.org/hg/dvb-apps is not maintained
for quite a while, as it depends on the legacy DVBv3 API, being
replaced by the dvbv5-tools, which are part of this repository:

	https://git.linuxtv.org/v4l-utils.git/

There, the apps are at:
	https://git.linuxtv.org/v4l-utils.git/tree/utils/dvb

And the libraries at:
	https://git.linuxtv.org/v4l-utils.git/tree/lib/libdvbv5


Not sure if the tool works with UK channel numbering. If not,
feel free to submit us a patch.

Regards,
Mauro.
