Now at my home, I have a 56" Sammy HLN DLP and a beautiful HD Tivo (HDR-250). Picture is spotlessly clean and even SD material looks great. I have the two connected via HDMI/DVI. Now I get to my mother's place, and I just recommended she pick up a Sammy DLP (her's is an HLP series I believe... purchaced at Circuit City about two weeks ago) and it seems there are some differences. She also has hers married to a Scientific Atlanta Explorer 8300HD via component hookups. I'm seeing absolutely horrid picture artifacting and certainly less than stellar SD representation. I've noticed that her TV model has done away with the Farouja chip that mine has and thought that might have something to do with it. I'm also going to pick up an HDMI cable today to see if it has to do with the D->A conversion. I switched her output to the native 720p of the display. I messed with some of the picture settings to try and improve the color and sharpness, but the artifacts remain and the picture is incredibly grainy. My mother is happy with the picture (and HD material looks fine) but her SD stuff is almost unwatchable (including SD material rebroadcast over HD channels like HD locals). Anyone have any thoughts as to a fix/what the culprit might be?
