It's her word against the tv man's - whether he did actually go into the house or not to check the telly was working. (Incidentally, you're not obliged to let these guys onto your property to check - so if you want to make life difficult for them tell them to come back with a police officer and a search warrant!)
Legally, if you have any equipment which is capable of receiving a tv signal (pc cards included) you're supposed to have a licence. She would have been more sensible to remove the aerial.
Legolas - yes we have cable - but you still have to buy the licence because it is associated with the receiving equipment, not where the signal came from.
Any licencing people out there who might trace this post - Emo does NOT have a television!!!!
