I did not realize until just recently that there are two types of component video inputs. What is the difference? (Can you not get HD signals through "standard" inputs)? And how do you know what you have? I have a 34" Sony XBR, and nothing in the manual tells me whether the component video inputs are "wideband" or "standard", though it does indicate that the inputs are compatible with 480i, 480p, 720p, & 1080i.
