Is... The Series 3 works! I have 2 series 3's, and they are flawless. My TivoHD, on the other hand, is unacceptable. It's super-pixelated, way too much to just ignore. I've hooked it up to the exact same set of cables as my Series 3, and the Tivo HD looks terrible. I'm willing to chalk this up to: a) Old software (the Series 3 I think had this problem prior to 8.3) b) Bad hardware (I might do an exchange to see if it's any better) c) Bad CC's (although I doubt this) I'm going out to return the TivoHD now. I have 7 (soon 6) Tivo's, and I love Tivo, so this is especially hard for me to do. But it's useless to me in it's current form. If I feel up to it, I might exchange it. Otherwise, I'm much more likely to buy another Series 3, if I can find one cheap. At least they work, and have been working for a year!
