Actually, in this case it's more than just "one layer of video processing".
If you're watching a 720p program (ESPN, all ABC and FOX family channels, etc.) and you have your Dish receiver set to put out 1080i, then the non-interlaced 720p must be interlaced and upconverted to 1080i by the Dish receiver. And if you then feed that to the 103 which has been configured to put out 1080p, then it now must be de-interlaced.
The visual result of these two really unnecessary conversions is very very apparent, especially when watching high-speed motion sports (e.g. tennis balls flying back and forth).
If instead the 720p (native 720p fed from Dish receiver to the 103) is simply upconverted to 1080p by the 103, it's quite stunning compared to vs. the two conversion result.
Note that many people just set their receiver to 1080i to avoid the 1-2 second "black" screen when browsing through consecutive program channels that alternate 720p and 1080i, as the brief HDMI handshakes to the HDTV and other devices in the HDMI chain occur when program resolutions change. I prefer not to concern myself with this, and I also just use the GUIDE to browse what's on right now (if I'm watching "live" which is essentially never) and then just go to that channel, accepting that there might be a 1-2 second brief black screen if resolutions change from the prior setup.
Anyway, if "native" exists as a setting (to automatically send source program resolution) then you don't have to get involved. If it doesn't exist and you have to manually change output resolution when you pick another channel or recording that has a different resolution than you were previously watching, sure it's a bit annoying. But again, the visual improvement of eliminating the interlacing/de-interlacing conversions is well worth this minor inconvenience.
