here is a great artcile about the XBR4 BUT IT EXPLAINES EXACTLY WHAT MOTION FLOW IS. THis is a great article read it it explains everythinghttp://www.guidetohometheater.com/fl...r4/index1.html
here are quick snippets
" TV ALWAYS runs at 120hz"
" motion enhancer activates motion flow and helps with up converting non 120hz sources to the tvs 120hz refresh rates""If the source does not contain 3/2 pulldown, such as a 1080p/60 video-originated source or a 1080p/24 film-based source from a Blu-ray or HD DVD player, Motionflow adds either one interpolated frame (1080p/60) or four interpolated frames (1080p/24) to each source frame to reach the 120Hz refresh rate required by the set's 120Hz operation. If you turn the Motion Enhancer off, each source frame is simply repeated as many times as needed to get to 120Hz, with no interpolation. "
"If the source contains 3/2 pulldown, such as 1080p/60 video from a film-based source, the 3/2 pulldown is not removed. Motionflow converts the 1080p/60 source directly to 1080p/120 by adding one interpolated frame to each source frame. If you turn the Motion Enhancer off, each source frame of a 1080p/60 signal is merely repeated once to reach a 120Hz refresh rate, but there is no frame interpolation"
"But the Sony's deinterlacing and scaling performance, with a 480i input, was disappointing. It performed poorly on many of the difficult video processing torture tests on the HQV Benchmark DVD (with the set's CineMotion set to either Auto1 or Auto2). .....Sony's own VPL-AW15 LCD projector, reviewed here recently, performed far better. So do many upconverting DVD players. "
"Sony's processing performed much better, however, when converting 1080i sources to the set's 1080p resolution. It still did not recognize and deal with 3/2 pulldown, but it did perform the deinterlacing properly and only rarely showed video processing artifacts with a 1080i or 720p source. And these were minor and fleeting."guess that means turn off cinemotion for your dvds and let the dvd player do it.
what a good find i made
interesting after comment
"Though "movie mode" presets are not new, Sony developed "Theater Mode" in consultation with Sony Pictures movie studio with the same team that works on mastering movies for Blu-ray Disc. Sony's TV design team went to the Blu-ray/DVD mastering studio with prototypes of the XBR4 model and tweaked settings beyond the user settings -- even the service mode settings -- to optimize the picture and ensure accurate reproduction of the intended mood of the original film when it was transferred."
hmmm even service menu tweaks, has anyone used there theater mode on teh tv?
