Okay, I have a few questions that I hope someone can answer or offer opinions on. My display is the Sony KP-57WS520, Sony STR-DE1075 Receiver and a Scientific Atlanta Explorer 8300HD DVR, 2 DVD players...Sony DVP-700NP and Panasonic DVD-K87S (which I'm taking back...not happy with it). 1. Would I see any great performance increase if I bought an upconverting DVD player? If I did so, do I have to connect that with HDMI rather than component? I only have 1 HDMI input, so the next question would be... 2. Would I lose any picture quality if I connected my DVR through component rather than HDMI? 3. If I buy a player that does DVD-A or SACD, will that work through digital optical out to my receiver? My receiver doesn't have any 5.1 or 6.1 (whichever it is) inputs broken out like on the back of DVD-A/SACD capable players. 4. Are there any carousel players that do upconverting yet? 5. If I were looking for a DVD player (carousel or not, depending on the previous question) that met these requirements (in order) what would that be? a. Picture quality (best, that is) b. Audio quality c. DVD-A/SACD (both is nice) d. Bells/Whistles (sleek looking, interface design, remote, etc.) Thanks for any replies. All of this is a little overwhelming!
