1) although technically it shouldn't matter which hdmi port you plug it into, some of us have found (on other pioneer avr's) that if you are getting a "green screen", it sometimes works better when plugged into the "last" hdmi port on the avr... hdmi and fios/cable boxes are still a hit or miss proposition, which is why when you get a "green screen", the customer service rep will tell you to hook it up component.
2) yes, hdmi carries the audio. what the note on page 23 means is that if you want to hear sound from the tv
(i.e. you are receiving ota signals directly to the tv), you need to hook up an optical cable from the tv to the avr in order to get the sound. when you are receiving signals from the fios box to the avr and then passing the video to the tv from the avr
, you do not need this connection.
3) any hdmi port for the dvd player will be fine.
here's how to hook it up...
fios box ---> hdmi ---> avr
dvd ---> hdmi ---> avr
avr ---> hdmi ---> display
as previously noted, if you have "issues" with the fios box (i.e. green screen, shifted pixels, and so on), you can hook it up with component and a digital audio cable (either coax or toslink)... this would be hooked up as...
fios box ---> component ---> avr
fios box ---> digital audio cable ---> avr
post back with questions if it's not clear....
