I have recently begun to experience problems with my Panasonic progresive scan dvd player (not sure of the model number, but I paid about 200 dollars and got it well over five years ago). Considering a budget of 300 dollars, what is the best dvd player to get at this time? Is it worth it to wait for the blueray players and spend more money? I have heard a lot about the "up conversion players", the denons and the oppo dvd player, but what in that price range gives me the best sound and picture quality? I am running it with a sony str-da5es avr. As always, thanks for the input and advice.
