Ken, you're right, I didn't know that. Which video processing chipset did Pioneer use in these displays? Can you point me to a professional review that documents the Kuros correctly de-interlace and frame double 30P video? I know these displays natively process 24P with 3:3 pulldown, but did not know they also handled 30P correctly. If that is the case, then it is a grandslam for Pioneer and effectively means the quality of the video processor in your BD player is completely irrelevant - you'd be best off leaving the player in 1080i60 output and let the display de-intlerlace, IVTC, and frame triple 24P material and de-interlace and frame double 30P video.
The issue of de-interlacing perfectly...Well Yves Faroudja essentially said it wasn't worth the hassle after selling his company to Genesis. Also, HQV documents right on their website that unless the video was originally shot progressively and the de-interlacer uses the weave method, then it is impossible to de-interlace perfectly (i.e., zero loss of resolution, no artifacts, etc.). Now, whether or not any of this would be visible in real world testing, I don't know because I don't know whether proper blind testing has been done. But I'll take your word that the Kuro's processing is very good nonetheless. I'd still like to see 30P documentation. The one thing that comes to mind after reading the HQV site is, "Why are we still dealing with this crap in 2008?!"
jjsaustin, according to preliminary reports of the HF10/100, yes, the cam is shooting a progressive image and then dividing that whole frame into two fields that should be able to be de-interlaced perfectly (weave) to reconstitute the original frame. The problem comes with the de-interlacing with progressive video equipment. I would assume my Sony XBR970 interlaced HDTV would have no problems recreating the original frame when fed a 1080i60 stream via a BD player.
The problem is with the progressive displays. Per my understanding (and the NIN 30P video thread is a resource here), the video is encoded as 1080P30 but flagged as 1080i60. So your BD player's (or display's if being fed 1080i60 from BD player) video processor must be smart enough to (1) ignore the interlace flag and (2) determine that there is no movement between fields comprising the original frame, thereby avoiding its complicated de-interlacing processing mode(s) (e.g., motion adaptive), and instead simply weaving the two fields back together, and (3) double the resultant frame rate to 60.
Read any of the more recent Secrets BD player reviews and you'll see they test specifically for this feature because 30P video is becoming more common. If Sony would have simply included 1080P30 in the BD spec, then the flags on the disc would tell the player what to do, the processor would not have to be smart enough to analyze the video for itself - just follow the rules, and there wouldn't be this hit-and-miss handling of 30P.
