I have a Zenith 1080i satellite receiver and a faroudja nrs-dvi and I have no trouble with HD channel pass-through. The faroudja also scalers up DVDs with a great picture, and it also scales up Over The Air channels nicely. However, I 'm have trouble getting the faroudja to scale up non-HD satellite channels. The unit has a sticker on it that say "NTSC ONLY." Is the faroudja suppose to scale up non-HD satellite channels?
