If I am right (correct me when I'm wrong, please) you abandoned SD2HD name and used some high quali scalling as default and some other technologies for Detail Boost. For me this is a good move, as IMHO "SD to HD", "SimHD", "TrueHD" and all others sound bullshit!
Detail Boost works really nice and DVDs upscalled to my HD iiyama display look much better than in other players.
