Hi, I have a Sanyo PLV Z5 connected to a playstation 3 via HDMI for blu-ray movies and an Xbox 360 HD DVD add-on for HD DVD movies through RGB computer input. Both look spectacular on the Z5 in high def but when I play a standard DVD on either the PS3 or 360 then the picture(edge) looks fuzzy. Both players upconvert(the ps3 through a recent firmware) the DVDs but it looks terrible.....I have read in reviews that the Z5 does great with standard def stuff but this sucks!.....is there something I can tweak or I'm just stuck watching high def stuff?......I want to watch my old DVDs but not if it's fuzzy on the Z5.
