All tested and confirmed working up here in the North East UK (Newcastle).
Thanks for your and the Tech Team's assistance.
For me all the suggested solution (removing .config for TV, restarting teamviewerd, reinstalling package ...) did *not* work. Even though internet connectability was good, TV did not display it's TV ID. After rebooting the machine I could relogon and a TV ID was displayed again in TV window. Looks like they messed up with some settings, and only a reboot fixes that, very verv very bad programming ...
