I don't understand what the major issue is here.
HDTV is either 720p or 1080i. Feeding either of those to the 103 where it then presumably gets upconverted to 1080p for delivery to your HDTV display accomplishes what you want, for best image on the HDTV display. My own experience is that the 103 does a better job of this 1080p upconvert (along with "cleanup", "picture punch", etc.) than any other device also in the relay chain which could do the same upconvert for display... including the HDTV itself. I have a Panny 65VT50 to go with my 103, and through experimenting and subjectively comparing results, I've decided to do the upconvert to 1080p in the 103 rather than deliver 720p/1080i "native" through the 103 and on to the HDTV where it would also get upconverted to 1080p for display.
Anyway, "native" out of the DVR is simply having the box automatically change output resolution delivered to the next component when the input source resolution of the program changes. But even if "native" is somehow not working for you, you still can do the same thing manually. Just change the output resolution yourself (either "fixed" in the setup menu of your Cisco DVR box which is fairly inconvenient, or by repeatedly pushing the FORMAT button on the front panel of the DVR box while you're using, which is obviously MUCH MORE CONVENIENT). This repeated FORMAT button use will manually cycle through the complete set of usable output resolutions, until you get to the one that matches the resolution of the program you're currently watching. This is really "native" result in that output resolution matches source resolution, but it was implemented by you manually rather than by the box automatically.
In other words, you don't want to have the DVR upconvert/interlace 720p to 1080i, and feed this 1080i to the Oppo 103 where it gets upconverted/deinterlaced to 1080p for delivery to your HDTV. This is two upconversions plus an interlace and deinterlace process. You won't like the results.
Instead, you want to have the DVR deliver 720p HDTV as "native" output 720p to the 103, where it gets upconverted to 1080p for delivery to your HDTV with ZERO interlacing/deinterlacing. Use the FORMAT button on the DVR to select 720p as your output resolution from the DVR.
And if your source HDTV program was 1080i, you want to have the DVR deliver 1080i HDTV as "native" output 1080i to the 103, where it gets upconverted/deinterlaced to 1080p for delivery to your HDTV. Use the FORMAT button on the DVR to select 1080i as your output resolution from the DVR.
That's what I do. Except that I don't have a DVR, and my HDTV "delivery device" is a Linksys DMA2100 (Windows Media Center Extender) connected to my HTPC... but the concept is the same, and there is no "native" available. So I have to manually switch output resolution on the DMA2100 between 720p and 1080i.
I've proven it to myself, that the upconvert/cleanup for 720p/1080i HDTV provided by the 103 makes me thankful I invested in this upgrade. Just feed it true 720p or 1080i (untouched, to match the source program resolution) out of your DVR, set the 103 to "AUTO" to do the upconvert to 1080p, and enjoy the 1080p results out the other end on your display.
