Due to a recent Comcast outage, both my internet and TV were down for about 24 hours. During this time, all of my Premieres became super unresponsive and kept freezing while navigating the menus. Ultimately, I was able to watch my pre-recorded shows, but it certainly was a chore. For the record, my older TiVos were fine during the outage. What's the deal? Why do the Premieres perform so badly without an internet connection?
