when i go to playback, it wont let me go to a certain time to watch it, it keeps going back to only what it recorded. i scroll to a certain time, and it goes right back to the recorded time. for example, i wanted to watch a cat run past at 10:04:12, i scroll to that exact time and it automatically goes back to 21:39:18. how can i watch the exact time i want without it going back? thanks
