I have a toshiba sd3205 5 disk DVD player. It is connected to a toshiba 50hx70 through a Harmon Kardon AVR510. I have been condsidering a toshiba 4700 progressive scan DVD player and was wondering if it would make much of a difference. I am not unhappy with the current DVD player but I have been considering buying a dvd player for my upstairs TV. I am wondering if I should buy the 4700 instead and just move the old DVD player...or just buy a cheaper DVD player for upstairs ...comments??
