Hi @wrinkle, thanks for your post and really sorry you're having problems using our TV service.
Just to be clear, can you see the Tivo menus on your TV or when you refer to only being able to access Freeview channels, is this from your own TV or via our Set Top Box?
If you can't see any Tivo menus, you might need to find the right Source/Input relevant to what your Tivo box is on, as per @newapollo's earlier suggestion. Can you confirm if you've tried this please?
If you are on the right source, and can see the Tivo menus, are you getting any error messages on channels such as Sky Sports that don't seem to be working for you?
Regards
Tom_W
