Has anyone else noticed poorer quality 1080i upconversion of 480i source signals on the Elite than on Series 3 or non-Elite Premieres? It seems as if the interlace is not upconverted properly and so vertical borders degenerate into stripes. The effect is subtle but quite noticeable on bulletin board or news channels that feature a lot of text. A capital E of a certain size will degenerate into a vertical bar with numerous horizontal stripes to the right. This happens on two different Elites, one ordered from TiVo and one I picked up at a local Best Buy, and it happens with both HDMI and component output. But it does not happen on either of my two Series 3 HDs or a non-Elite Premiere Im testing. Native 480i output is fine, as are 480p and 720p upconversion. Only 1080i output of 480i sources seems to be affected.
