I also have the Sony BDP-S300. It replaced an Oppo standard DVD player, one of the expensive models with 1080i upconverting capability. I was very happy with the picture from the Oppo, but the standard DVD upconvert on the Sony BluRay puts it to shame. I don’t know if it’s because the Sony upconverts to 1080p, or if it is something else, but a standard DVD played on the Sony looks terrific on my 52” LCD flatscreen. Not quite as good as a real BluRay, but pretty darn close. Close enough that I would never consider replacing a standard DVD that I already own with a newly purchased BluRay version.
