That a card, with specs only indicating 1080i, can display 1080p just fine, doesn't surprise me at all. What's happening is that the 1080p picture is indeed carried over as 1080PsF (with fields offset time being zero, as they're taken from the same frame of the progressive source).

The same principle is used for burning BD's from 1080/25p (or 30p) material, even tough neither is in the BD specs. After having edited my 1080/25p source in Vegas, I always encode into 1080/50i m2v's for DVDA, and burn BD's which don't show any typical interlace artifacts (like combing) even on a PC monitor, which is of course progressive and doesn't do any deinterlacing (as HDTV's can do).

PS BTW, when you hook up a progessive camera (like the EX1) to a full HDTV using component, the same thing happens - both interlace and progressive content is seen by the HDTV as 1080i, and NOT 1080p.
