The problem was just on the HD (S3 actually). The Premiere was fine. Moving the cables around had no effect on the Premiere. When I first connected the S3, it was not having the problem, where in the past it was almost constant. I watched the S3 for a few minutes and did not have a single instance of pixelation. I then placed reset the TiVos in the cabinet as they should be. Then the kids watched some TV, but were watching on the Premiere because the S3 was recording stuff on both tuners. Later when I tried to switch back, the picture was back to pixelating. I was thinking it could be related to the HDMI connection, but that seemed unlikely because the sound is a separate connection to my audio system and it has problems at exactly the same time as the pixelation occurs. Are the power supplies between TiVos interchangeable at all? I have a TiVo HD in another room (same model series as the S3). Any chance I can try that power supply in the S3?
