I was wondering if there were any good web sites to show comparisons between "normal" (480i) and then HDTV (1080i or 720p) pictures? It would be great to have some Super-bowl comparisons because of the extra view of the field, but anything would be great! Also any basic descriptions of the difference would be great too. I am trying to sell HDTV to everyone I meat and would love to show them some comparisons. Thank you in advance!
