For digital television there is no acceptable quality - you either get it or you don't unfortunately. If you get a bad signal with analogue TV you get a bad picture but if you get bad signal quality with digital television you get no picture. A signal booster probably won't help though - signal quality for digital tv bears no relation to signal strength - some of my digital channels have 60% signal strength with 98% signal quality, others have 90% signal strength with 40% signal quality. Looks like the aerial you are using isn't good enough for digital TV reception and as you are in uni it's probably not something you can fix easily.
Sorry to be a downer and all, hope you get a resolution.
Thanks for the reply guys, it never occured to me the fact its digital and not analogue, makes sense as to why it wouldnt accept a lower quality signal.
So getting a cheap analogue card would pritty much rectify the problem, allowing me to watch TV, but at a loss in picture quality?
People responsible arnt interested, crap signal seems to be running throughout the building. They just say theres nothing we can do about it.
Freeview isnt avaliable in this area, but id only be after the basic 5 channels(beeb1&2, ITV, channel 4 and FIVE) - in theory an analogue would do the trick though?
