Hi all I am new to this and this is my first ever post, basically I am changing from a Pioneer DCS333 HTIB to a seperates. I will be getting the Onkyo TXSR 505E receiver, a DVD player (undecided,something around £100-£200)a panasonic th37px70, Sky HD box and 5.1 speakers. The Onkyo states I need to connect a seperate audio cable for surround, would this be a coax digital and will I need to do the same for the Sky HD box ? I intend to use hdmi into the receiver for dvd and Sky hd and hdmi out to the tv. Any help appreciated. Am i on the right lines !
