Wow. My last log in was in 2007! Well I'm back with a new Tivo Premiere. I'm using antenna only input (bye bye Direct TV) and experiencing 'stuttering' video signals. It seems to happen when there is a lot of motion in the image, watching football is a classic example. I tried a direct input from my antenna to my TV and the signal is good, no stutter, or judder. So it's not my signal or tv. Ideas? Do I have a bad Tivo? Has anyone else experienced ota signal issues with the Tivo?
