Advertisements Live TV loses about a minute per hour on both of my Series 2 TiVo units on all channels on Comcast. This means that if I leave a channel selected at night and turn it on in the morning, it will be 10-15 minutes behind real time. Pressing the Live TV button does not cause the channel to catch up; I must change the channel and come back to be in real time. If I watch closely, there are glitches of a second or so every few minutes--I surmise that this is how the time is gradually lost. Status shows I am running software 9.1-01-2-540, updated in mid-October 2007. It is mid-November 2007. I noticed the problem a week or so ago, but it may have been happening longer before I noticed. I have had the units for three years or so; this is the first occurance of the problem. "Sorry I'm late for work, my TV was running slow!"
