Hi there I have Netflix and watch it via apple tv on my 46 inch Sony Bravia LCD tv. I currently have sky broadband but only get a speed of just over 4mbps. I find the picture quality pretty poor on standard definition and only adequate if playing a HD stream. The quality is very good on the small screen iPad. My question is if I upgraded my broadband to fibre 40 Mbps would it upgrade the picture quality or not...
