I have a DVD Player with 5.1 output and recently a SHARP 66FW-54H with Dolby prologic. 4 speakers plus TV internal acting as central were connected to the TV output. I was receiving good (in my humble opinion) quality sound. The TV broke & is irrepairable but the extended warranty has offered me a SHARP 28HW53H with only Nicam sound. 1. Should I accept? 2. What other hardware will I require to get Dolby surround from my DVD & Sky Satellite signals? 3. Is there anything else I should consider? 4. Is it all very confusing or is it me? Thanks Jason.
