I have Sony 5.1 AV Receiver with no HDMI ports but Digital Coaxial and Digital Optical ports, I need to hook up all Sony AV Receiver, Sony Mini Disc, Sony DVD Player, HD Set Top Box with Samsung UA55F8000 HDTV (UN55F8000 American Version)? By the way do I have to use so called All in HDMI Converter box to hook all these? I'm using Bose Acoustimas 10 II speakers. Can you suggest me please.
