1) I heard that the HDMI cable signal degrades if the cable is over a certain length, lke over 1.5 metres. If HDMI is a digital connection how can it degrade over such as short distance? 2) I see many tvs that say they play 1080p. but they dont have HDCP, so therefore if you play a blu-ray your picture quality will be downgraded. If you have a copied blu-ray movie where all the copy protection has been taken out, will the picture still be downgraded? 3)The signal between a normal dvd player and a tv is analog if you use a component or composite cable, so therefore the picture quality is degraded. But if you use a dvd upcoverter it keeps the signal digital between the tv and dvd player, but is using a up coverter provide the same picture qulaity as if having a dvd player with a HDMI connection? 4) How much resolution does an upconverter improve on a normal dvd movie, does it make it 1080i?
