My new system Denon 3806 Receiver Denon 2910 DVD Phase Tech PC series speakers SVS PB-12 Plus MX 850 remote I have a older (4yrs) Mit. Diamond 55 and it does not have hdmi or dvi connections available, but one component input (DTV). So I plan on running component from the receiver to the tv - Should I use the denon link from the DVD to the reciever? If so does it handle both audio and video, or do I also need component cables for video? For the xbox and the satelite receiver should I use component for video and optical for audio? I appreciate you time Barry
