To be specific, my sample of the XD-E500 actually dropped half the fields and upscaled the rest. Thus, I ended up with an effective 720x240p30 video with fully half the picture missing entirely. (I noticed this in the small text that’s been broken almost to the point of complete illegibility.)
The one feature that Sony’s Blu-Ray players (and those of many other brands) really need is the automatic output switching between 1080i60 and 1080p24: On a Panasonic Blu-Ray player which supports this feature (or a player from certain other brands with a similar feature), you set the output resolution to 1080i and the 24p mode to AUTO, and the player will automatically determine the best mode for a particular Blu-Ray disc. With the Sonys (and many other players), one must manually make the switch using the players’ on-screen menu system since selecting 1080i as the output on those players would disable 24p output (or conversely, the output resolution must be set to AUTO or 1080p in order to enable 24p output).[/QUOTE]
I forgot to mention that the XD-E500 drops every other field and passes through (but does not upscale) what remains. What’s worse, it performs this incorrect deinterlacing before the upconversion, resulting in the deinterlacing flaws becoming painfully obvious. The larger the screen and the higher the screen resolution, the worse it looks. This is how I got this blurry, flickering mess from video-sourced DVDs.
The so-called “24p” mode on the XD-E500 is, as others have stated, largely a simple 2-3 pulldown. However, unlike most other upconverting DVD players which resample the frame rate of 24p-encoded DVDs to 30 fps before outputting to the TV set (those other upconverting DVD players actually perform a 2-3 pulldown removal to get 24 fps but then interpolate that to 30 fps since their progressive-scan output is permanently fixed at 30 fps), the XD-E500 could output the result as a 24 fps stream. But I never tried this feature since I had only a 60 Hz HDTV set when I had the player (I still have the very same set for the present but might upgrade to a 120 Hz set in the near future).
Also, that automatic-24p-switching is the default mode on the PS3. It cannot deinterlace 1080i material at all.
