Our X1 DVR has started jumping back 15-30 minutes after we’ve paused it for a few minutes or backed it up a little bit. When we start to play again it jumps back. Then we forward to where we want to be and it’s fine for a little bit. Even once we’ve caught up to live it will jump back 15 minutes when no one is touching the remote! This seemed to start once they introduced smart fast forward or whatever it’s called. We had it on one show and never again but that’s when this started. Is the DVR broken or is this a system problem?
