Hi all, new to the forum and I have found all the posting really useful. However I have not been able to determine the answers to the following questions that are bugging me in terms of making my purchase. Can you help please? o What does the 56 have over the 50 or visa versa apart from size and does it matter? I have the room for either TV. o What do the letters after the size number depict e.g: B, F, H or T and G4 etc? And do they matter for my decission? o I already have a DLP projector for most of my movie viewing, I want to view mostly sky broadcast (not HD yet). What effect will this have on a 56 or a 50? o I've read rumors of the newer Autum models, should I wait? Many thanks for you help.
