I'll start with what I have to make things easier.. Sony Cineza VPL-HS20 projector with DVI/Component/HDMI/S-Video/Video inputs Sony ES STR-DA5000ES receiver usual high end connections no DVI though. Sony ES DVP-CX777ES 400 disc DVD/CD/SACD changer usual high end connection no DVI though. The native resolution of the projector is 788p if I use the Component out on the DVD player resulting in a 480i/p how do I achieve a 788p resolution on the projector to get the utmost quality from it? Sony says that the projector can convert HDTV, as well as all other signals, can be converted by internal scaler so that they precisely match the projector's 788p native resolution. So if I understand that correctly I do not need some type of DVI out or converter to acheive the best results from my projector? Also the back of the changer has optical/coax and 5.1ch output...am I correct in assuming that for DVD I should use the Coaxial or Toslink output and to enjoy SACD I use the 5.1ch output? So basically I need to have both those connections made to the receiver at all times for both? Great forums here btw..ive been looking thru numerous posts getting ideas and getting alot of info.
