right i didnt read the whole of the first post, mainly because it didnt make any sense to me, but i gathered it was a query about having a TV license in halls etc.
Basically you're MEANT to have a TVL for every TV in the house, hence why if you buy a TV under your name, but someone else in the house already has a TVL you still get sent letters telling you you need one too.
Secondly, you need a TVL for ANYTHING that recieves TV signals, be it a TV or a tv card in ur pc. No they can't burst into your home without a permit, but even if you had one TVL between the lot of you it's better than nothing surely? and what's £125 between 7-10? not a hell of alot.
