A couple of days after the event you can easily do that so I assume that is not what you are talking about. On the day of the event you can generally skip all around the entire event from the point you started to the point you stop (on a single PC) .... if I recall correctly you just can't let the event come to an end (it then limits rewinding) ....but as long as you say go back to very early in the event you are good to go.
I often watch in my shop, my racecar trailer, and while mowing in a tractor ... I use the shop as the one that stays on all day and I'll sporadically rewind. The other two, I come and go so much that I rarely deviate from the live feed (and the tractor ride is just not that smooth with a touch screen!).
