Grandsport on my NR818 what I do us use two inputs (sort of). On tbe 818 use the "dvr/stb" as your main hdmi input for DD 5.1 but also connect some analog Rca audio cables from the stb to the "TV" input on the 818. The "TV" input can use hdmi for video and analog for audio. Then just depth between the two. I highly recommend using neo-x on the analog input. Just remember to duplicate your video settings between the inputs (if you have any). Also the sub will need to come up a bit on the "TV" input using analog.

With neo-x and analog unless I'm watching an action show theres not much reason to switch between them. once you have everything tweaked switch back and forth between a sure in 5.1 and the analog with neo-x. You'll be shocked. While not as good it's 80% I'd say.

They need to address the video issues on the 2250, hopefully the next release they will.
