Here is my issue: I have the Oppo BDP-83 BR player (love it!) but I also have a multi-disc (5) upconverting DVD player from Sony. Now that I have the Oppo is there any reason to keep it? My previous line of reasoning was that I would use the DVD player for DVDs (380+) and use my Oppo for my growing BR collection. I figured I would keep mileage off of my Oppo. A friend of mine who also has the BDP-83 says I should worry about "the mileage" factor and that my old DVD player is a useless component. What do you guys think?
