I don't think you understand what Native means.
Yes, I do, but if you de-select 480i as an "available resolution" (which is what I was talking about), then the DVR doesn't try to output 480i even if the channel is 480i. That part is fine. The part that isn't fine is that the DVR will always pick the next highest resolution that is checked. This actually happens for any de-selected resolution, but it really only makes a difference for 480i, as the next two resolutions are both 60fps progressive, which is not the best target when converting a 30fps interlaced signal.
I don't have 480i selected as an available resolution (even though my TV can obviously handle it) because that means that if I am watching an SD channel, not only is the UI is SD, but it is confined to the 4:3 area, which is really ugly, as the UI is designed for a 16:9 aspect ratio. This means all the text is tall and skinny. Add to that the low resolution, and it's a lot harder to read. But, I want 720p and 1080i output natively, as that gives the best picture.
The other picks that result from the "next highest" are fine...480p->720p is an easy scale, and although 720p->1080i isn't the best choice, it would only happen if 1080i was the only selected resolution. A better output choice would be 1080p (if available), but as I noted, that never happens despite the chipset being able to handle the conversion. And, that's really what got me to post in the first place, because what I really want is to be able to do is to only output 1080p at all times.
