I think the subject DVD players are one and the same. My wife bought me the sd-k700 at costco. Bless her heart but I am think about taking it back and buying the panasonic RP91. I have heard the Toshiba has the Chroma bug, but besides from that is this a wise move? I have a Panasonic CT34WX50 it has the 16:9aspect ratio and thisi would be my first DVD player so I do not have a reference point. So what do you say? Keep or trade up?
