Do I need an outboard scaler/deinterlacer with the 10HT?
A deinterlacer, also called a line doubler, simply converts 480 line interlaced video to 480 line progressive video. A scaler then scales the image up to the native resolution of the projector. The 10HT has both a scaler and deinterlacer internally, and both are quite good. However, the Sony deinterlacer does not appear to recognize and undo 3:2 pulldown, such as you would find on video that was originally sourced from film. Some outboard deinterlacers do in fact detect this pattern of fields and are able to do a better job with film material. If you want this capability for all your sources, you may want to look into getting a scaler such as the DVDO IScan+, the AVScience CrystalImage, or the TView Quadscan Pro. None of these units will be able to bypass the Sony’s internal scaler, so the image will be scaled twice. The preferred output formats, from most preferred to least, are 720p, 1080i, and 480p. Note: The IScan+ and the Quadscan (and probably the CrystalImage) will only output c
