I completely agree with your last statement. Haven't had my zippered units plugged into a phoneline for the past 2 years. I haven't had a single problem with either of my DTivo's, even during the Daylight Savings time goof that some had to deal with.wedgecon said:I was just interested. I had a friend who's Series 2 was still on 3.1 because it had never been plugged into a phone jack. I am starting to think of all the little glitches over the years could have been avoided by just simply not letting the DiredTivo's update.
