View Playback doesn't move to new time

When I move the time scroll to a new time the playback stays with the first selection. For example, if I select 10 am then click play I see 10 am recording, then I move the scroll to 9 am and the video still shows 10 am. So I click stop, and it stops, then I click play and it continues at the 10 am and not the 9 am where the pointer on the scroll is. I then move the time scroll to 8 am and still the video shows 10 am video, I once again stop and play and still video plays at 10 am. My app has the latest version. Am I doing something wrong or is this a bug?
