The first switch off of the Analogue signal in the UK starts in October, so if you using Media Center with an analogue TV card you should think about getting a nice new dual DVB-T (Freeview) card.
Ok its just in Whitehaven where the seagulls outnumber the people (just a joke folks from Whitehaven!) but its the start of the switch off process.
"The countdown to a digital future has begun," said broadcasting minister Shaun Woodward. "In October, Whitehaven will start the process of digital switchover. Residents will be able to reap the benefits of a greater choice of TV channels and better quality pictures and sound."
