I am having a time figuring out the best way to connect the following: LG 26XL1D TV (non-HDMI) Hardom Kardon AVR254 (HDMI) LG BD630 Blu Ray player (HDMI of course) HD DVR Receiver from Comcast (HDMI) Even though the receiver is 7.1, I will only use a pair of Mission 774s in the front, a Mission Mh-3 Center and a pair of Mission 2 Way Reflex with a Veloyne VA 1210 sub.
