First post guys - so be gentle. I' m about to set up my newly purchased HC kit for the first time. I've bought a Denon 2105AVR and have also acquired a Mission FS1 AV speaker system. These will hopefully compliment my Sharp LC30ADIE TV (fairly new) and a Toshiba SD210E DVD (fairly old but stilll working well!) Several questions being new to HC (although I've done some reading): What are the advantages of routing everything (video and audio) via the AVR - apart from the on screen menu for the AVR set-up which I guess I could do temporarily via the AVRs monitor output to one of the Video Inputs on the TVs separate freeview tuner box? Surely the audio aspect is all that needs hooking up? The RGB scart from the DVD to TV gives an excellent picture, better than the component connections (which are available on both) according to some reviews I've read for this particular TV. I'm using a good quality QED Squart. Can I still maintain this connection and separate the audio signals via coax or optical or do I have to invest in component connectors and possibly sacrifice picture quality? What is the better digital audio hook up - via coax or optical? One's electrical the other uses fibre right? The TV also has an optical audio output and the DVD player has both. Am I right in thinking if I route the TV's optical audio output through the AVR I can listen to broadcast TV via the Missions too? What about speaker positioning. Given these are NXTs do they still need to be around ear height for the front three and the two rears up high on the wall? I obviously dont want to spend a fortune on unnecessary cabling and connectors but will buy good quality for what I need. Thanks for your help.
