I know this doesn't give TOTAL minutes of lagtime from livetv, but I think this is an even better feature:
when you hit the rewind button (two left arrows) on your FiOS TV remote, it tells you the actual time of the recorded segment as you're scrolling back. So, if you have the current time, then you can easily see whether the recording is near the beginning or middle of the show.
Hope this helps!
Ok, thanks! That will indeed let me calculate how far behind I am. I recently switched to FIOS TV from dish and so I'm still learning all the features. On Dish, when you are paused, it continually shows you how far behind Live TV you are. I may post a new feature suggestion.
