I think that may be a bbc channel, one of the ones used for the "alternative " viewing options. I read that as part the changing structure on freeview, some would be discontinued.
When I go on the red button to watch alternative snooker the menu still gives 2 options for the available matches. However with only channel 301 available I can only get that one.
If 302 has been cancelled why are there two options listed?
I am using a seperate Freeview box and analogue TV set.
