I am still using the older comcast HD dvr something something-6412 with the DVI output. I am only using the comp outputs, because my TV doesn't have DVI in, but has HDMI inputs. I am thinking about swapping it with the current version of HD dvr that has a hmdi output. Anyone else did a samiliar upgrade, did you notice any picture diff between the 2 units?
