My brother asked me an interesting question today that I will relate to you because I don't know the answer. His daughter was watching the DVD Alladin in 480P. It just so happened that that same movie was brodcast over HDtv that evening and he said the picture was MUCH better than his dvd. This could be expected as it is HD vs ED. But what got us both is what source material are the broadcasters using? Why are they able to broadcast movies in true HD but the best the DVD can produce, and which is available to us, is ED?
