Elizabeth, you completely gone the other way of what Aberyclark was saying. He said Video quality only(audio conversion and your Oppo 83 player is a different subject for another day). What's with the Oppo 83, this subject was beaten to death every day here on Agone, enough already. Now back to the question, make sure your player can put out 1080P quality. That's the STANDARD display for true Blu-Ray dics, as long as it does and your HD display as well, yes the pictures quality are as good as they can get. The Audio conversion that's another story for another day.
Technical Question
I know if I use the "analog audio" outs of a CD player, the actual player is doing the DAC. If I use digital out (optical, coaxil), the receiver will do the DAC. Now, does the same apply with video? If I use the HDMI connection on a blu ray player and connect to my TV, does the TV do the actual video conversion? Just curious...If the TV does the conversion, why spend more on a top line BD player (disregarding features...just talking about video quality)?
