We have the newer ED model with several composite sources (LD, cable, VCR) switched through a receiver, and one component source (Denon DVD-1600). I wanted to ensure that the composite input was calibrated for the best PQ settings, so I added a composite cable from the DVD player to the receiver so I could switch the interlaced DVD output as well.
A strange thing happened when I started adjusting picture size/position. When I output the Video Essentials over-scanning test pattern on the component connection (interlaced or progressive), I get no image cropping (this is consistent with the hometheaterhifi shootout's results of the DVD-1600's pixel-cropping performance). However, when I switch the input on the plasma to composite, there is a bit of the image on the right side of the screen that is not displayed. I've tried adjusting the size of the image using the panel's size/position settings to reclaim the lost portion of the test pattern, but the image itself simply isn't there. Granted, the picture loss figures in at less than the 5% marker, but it's not symmetrical on both sides of the display. On the left side of the display, two hash marks are visible past the 5% line, on the right, there is only one--and since this player doesn't crop any of the image (at least on component), I can't figure out where the problem might be.
Has anyone else noticed this effect? Is it possible the DVD player has different pixel-cropping performance depending on which output you use, or could the plasma be cropping the image based on which input it's fed? Since I don't watch DVDs via composite, DVD image size isn't that big a deal--color/tint/contrast/etc. were the settings I was really after--but now it seems like I might be missing part of my SD signals (slight though it may be). I guess I should try tracking down another DVD player to be sure--but I was hoping someone else might have the time to check their display and just see if they got the same kind of behavior...
Thanks!
