I am seeing horizontal glitches in my preview window when viewing panned shots. It appears that there is a temporary misalignment of horizontal sections of the video. It does not do this when not panning. Changed tapes, and tried changing preview quality, but no significant difference. It does not appear to occur at the same point each time, and I do not see it when viewing each frame separately. I am hoping this is just the inability of my pc to keep up with the panned video in the preview screen. Any ideas?
