Try Investing in Sky TR
If you have the spare money its worth it as freeview blows
Not sure where you got the idea that Freeview blows, but as someone who used to be part of the development team for TopUp TV, it is fantastic considering it is effectively free, and locally is even better now since the signal power was increased and capacity freed up with the DSO. Sky customer service blows when they have their usual billing cock-ups... no such problem with Freeview... you don't have to line Murdochs despicable pockets with £30+ per month of your hard-earned, just to watch TV.
Having used both systems, they have their pro's and their con's, but overall, Terrestrial is actually the more reliable, because an ariel does not have to be positioned so accurately to receive a signal.
Anyway, the problem is likely the ariel; is it external or internal? If it's internal, what model is she using?
There is a fight between Moel Parc and Winter Hill... but you should not be affected by it, unless you have the ariel position in a certain way. Depending on natural factors (weather etc) at the time of scan however, you may pick up the Welsh variants alongside of the English variants.
