Hello.... Just started getting my home theater going....nothing TOO crazy...but deffinitly pretty good. specs: 58 inch Panasonic Plasma the HTR-6090 A/V reciever JBL Studio series speakers monster cable and so on... with that current setup of mine will Dolby True HD work? Will i need to get 7 speakers becuase its 7.1? I only have 5.1 right now. and why do you have to calibrate your plasma...Never heard of that!
