My understanding is that most receivers simply "pass through" an HDMI signal, unmodified, yet receivers will upconvert lower-resolution analog (component) signals to 1080p. If I have an Xbox360 that has an HDMI output available and I'm running it through a receiver like the Denon AVR2809CI, does it make more sense to actually run the component video cables so the receiver will upconvert the video to 1080p? From what I read, the Xbox360 is only capable of 720p or 1080i output. Or do you know if this (or other mid-range receivers) will actualy upconvert an HDMI source? Thanks in advance.
