You're talking about several things at once here:
There are only three DVD players that can "1:1 pixel-map" at the moment - the Bravo D1/D2, the Momitsu V880 and the SnaZio. They do that by providing an explicit pixel-map over DVI/HDMI, ie. 852x480 pixels. You can also do it with an HTPC with a DVI connector and the right software.
480i is not pixel-mapping, by any definition. Neither is 480p, 720p or 1080i. Neither are VGA, or component, or S-video or composite connections.
The SP4805 does not accept 480i/576i via the M1-DA port. The builtin Faroudja processor is not active on the M1 port, only the discrete analog ports. The M1-DA digital port will accept 480p, 576p, 720P and 1080i as well as various VGA resolutions but none of those are "1:1 pixel-maps".
You cannot successfully feed 480i/576i to the SP4805 in a digital format. Infocus specifies that the M1 port is "progressive only"
