I am having hdtv installed today and saw that on the back of the Samsung DirecTv hdtv receiver that it has a 480i/480p input. I was told that it is to hook up your dvd player through. I was also told that it upconverts your 480i/480p signal to 1080i, is this true? And for those of you who have it hooked up like this, do you notice a better,same or worse picture than when it is hooked up directly to your tv? Why this is an issue is due to the fact that my hdtv only has 2 component inputs. I am actually looking for a good high bandwith video switcher but was wondering if this way will work good until I get one?
