"Show Hide Elements" movie Clips continue to play

Question

I've put a bunch of AP Div tags on a page with video links,
once one begins to play it continues after another thumnail is
clicked. So, a user can soon be bombarded with audio from 8
different clips playing all at once, because once one begins
playing, it seems to not "hide" or cease to play as it should.
The URL in question is found here, but you have to click the
link for more demo reel stuff to load the page I'm trying to work
on:
http://www.knappmediaproductions.com/portfolio.htm
Remember, click where on the page it says: "More varied
examples of Demo work seen here" to open the page I'm dealing with.
Is there code of some kind to shut all those clips down when
the layer they are on is hiding?

Answer 1

I understand that you can remove one parent instead of many
children in this way, which is good from an efficiency standpoint.
Beyond that, I was ideally looking for a way to basically "freeze"
the action on Frame A and return to it. I assume that, even with a
parent-child scenario, I would still need to loop through all of
the children and save their states (because just checking the
parent attributes isn't going to get at this information). I was
just asking if there was any easier way. It would be nice to be
able to go to another frame - maybe on another level - and then
come back to Frame A and pick up where I left off - just hopeful
thinking, I guess.
