That's funny (well not really) but I think I am seeing all of a sudden the SAME thing with my C.I. and G1000 combo. Purchased the scaler in January this year and had never seen this until the last two DVD movies I watched in the past week. I happen to live within driving distance of the mfg / service facility in Chatsworth, CA and was actually over there today with the unit for a couple of reasons. One was that I had inadvertantly screwed it up by getting the power "auto on" function activated and then not realizing I was continuously resetting the unit to factory presets that were not my normal outputs when I would hold the power button on manually for a couple of seconds trying to use it. The nice person there at Audio Video Source, Inc. squared me away on it while I waited and even plugged in the latest software chip....5.6 or something.
However, at it seems exactly the same time as these problems started with me and the unit around a week ago, I also began noticing what you are describing on DVD playback, either with component or Y/C input from the player. And it IS hard to describe.....kind of horizontal faintly colored ghosting or trailing, as you described it, the full width of the image, cued from movements of people usually, only on certain scenes. I also mentioned this to the technician but we didn't set it up and try to duplicate with a DVD player, both of us assuming that I had been the source of any of the recent odd behviour, with the power button / resetting thing.
I watched the Lakers tonight with Y/C input from the cable box, and the picture was normal on the video based source. But at halftime I cruised with the channel remote through some of the standard digital HBO channels, and when the source became film based there were the horizontal ghosting artifacts again.
ppiazza, at least you and I seem to be looking at the same (all of a sudden) odd thing. Do you also not see it with video sourced material? Looks like I may be driving back to the service dept. with my DVD player to have them take a look at this issue specifically if I can't find a solution myself.
Anyone else have an idea what might be going on here with the film based source horizontal ghosting or trailing? I have the film auto detect mode set "on".
