So things like the PS3 can upscale dvd's to 1080p (and presumably 1080i), but can they show blue ray discs at 1080i instead of p?Obviously i'd like to take full advantage of the format, but at present my projector (Themescene h56) only supports 1080i, so would i be wasting my money buying a Blu-Ray player? Am i better off with e.g. the Samsung DVDHD1080P7 or DVDHD870?
