It seems to be a problem with the relentless drive to digital broadcasting. When it\'s working OK, the sound and picture quality is great. But when it breaks down for whatever reason it becomes unlistenable/unwatchable. However, with analogue broadcasting at least you can still watch a poor picture or listen to noisy sound broadcast.
Following this weeks announcement from the BBC/ITV who are going to enter into the digital satellite broadcasting arena on a free to view basis (but offering more channels than terrestrial Freeview) it will be interesting to see what happens to Sky subscription TV.
