Advertisements I just received a refurb Roamio today after complaining about pixilation issues to TiVo supervisor (and $49.95). Plugged it in and while doing the setup it tuned to channels perfectly with no pixilation then a notice comes up and says that it is updating and after about 30 minutes the same problem that I had with the old Roamio unit pops back up. How can I UNDO this update? PLEASE RESPOND TIVO SARAH!!!! nI've had the cable company out 5 different times and even took my TIVO to their headend office where I still had the same problem with pixilation!!!
