Is there a fix for the problems with rewind and fast forward functions? It is almost impossible to start and stop at a spot to resume viewing.

I’ve had the same or a similar issue.      Sometime when I try to scroll back in time in a live show it instead goes back to the furthest point in time and won’t move from there.    The only fix at that point it to do a reset on the box or power off and on      Been like that for well over a year.    No.   I haven’t swapped out for a new dvr box because that’s not worth the hassle.
