As far as SD channels, it is my understanding that they are native 480p and they do look best when the STB is set to 480p but 95% of my viewing is HD channels so I just leave the STB set to 1080i. BTW, the CC input looks better in all instances.
Yeah the Kuro will almost certainly handle the processing better than any set top box so the theory is to feed it as unprocessed a signal as possible and let the Kuro work its magic. Some HD channels broadcast in 720p and some broadcast in 1080i. If you have your box set to output 1080i only, then it is upconverting any HD channels that broadcast in 720p and of course, any SD channels. So in those instances, your box is processing that signal and then passing it on to your Kuro where it gets processed again. Now you and I have different boxes and the way you have yours set up may be best for your situation. I have found on my SA box that the 720p channels look better when I pass them through at 720p. My box lets me pick 480i, 480p, 720p, and 1080i output. I select all of them and the box passes on the signal without any upconversion. The only downside to this that I've found is channel changes take more time. For example, if I switch between a 1080i channel and a 720p channel, the Kuro has to adjust the input resolution which takes an extra second or two. It bothers some folks but not me.
Now to your cablecard problem. I don't have one but I do have two coax cables running from my structured wire panel to my Kuro. One to the cable box and one to Antenna 1 on the TV. I have flipped back and forth between Antenna 1 input and cable box to compare image quality and have noticed a slight improvement with Antenna 1. It's not huge but it's there so the box is obviously having some effect on image quality. I'm guessing your box is doing the same.
