My display is an older Tosh 57HDX82. I am in the market for a new DVD recorder and I see the information for the upconverting models. Would these be useful for the quality of display on my set? I believe my set itself can display 1080i/720p, but not full 1080p. Does the set itself upconvert my standard DVD signal from my old Tosh player to 1080/720 already? Would I see any improvement with an upconverting DVD player/recorder or would it be the exact same? Thanks for any and all assistance and advice.
