This is based on a prior thread, but I thought it an important enough issue to create its own thread so that the powers that be at TiVo will see it. I, like many others run my HDTV at 1:1 pixel mapping for a sharper image. This, however, is akin to what we video professionals call "underscan" on video monitors, allowing us to see the entire raster. As many of us have noticed, very often Vertical Interval Timecode or Closed Captioning, or other broadcast data is visible when viewing SD material that is resampled up to HD in either the 1080i or 720p fixed modes. All TiVo really needs to do is to somehow crop the two 2-3 lines of those images and that annoyance will be gone. There is nothing visually important up there, as every professional TV production person in the world knows not to use the outer 5% of the screen for anything important. My guess, and without a waveform monitor at home. is that all TiVo needs to do is crop out all the lines up to line 21, which is the first line of actual visual content, though a crop to line 23 would safely deal with some of the variances in vertical delay or misplaced data.
