AS3, 33rd FLV loaded loses sound: with solution

Question

Loading FLVs into an flvplayback component, the 33rd FLV
loaded is silent, and no FLVs loaded after this will have sound.
I had assumed that as the instance was leaving the stage and
it's parents etc were being deleted, and there were no persistent
references to the content, the player would deal with garbage
collection.
It seems this is not the case.
I don't know why the 33rd is the one to fail, but I guess 32
might be the maximum number that work?
So, if loading multiple FLVs into your movie, remember to
manually close the FLVs once they are finished, before loading the
next one.
I used
myFlvPlayback.getChildAt(0).close();
you could also use
currentVideoPlayerIndex =
myFlvPlayback.activeVideoPlayerIndex;
myFlvPlayback.closeVideoPlayer(currentVideoPlayerIndex);
but I found that this errors when you have only loaded one
video, as you can't closeVideoPlayer where the current index is 0.
I can't find anywhere in the documentation that states that
you can only load a maximum of 32 videos into the player, perhaps
it's a sound channel limitation? It would have been helpful for
there to be a note of it in the help files!
Maybe I should have known to manually clean up anyway, but
hopefully this will save a few people a few hours of head
bashing.

Good question!
They are all being loaded into a single component. However,
the component is in a MC being attached dynamically using "new
VideoPanelClass()" (the name of my specific class for the MC that
includes the FLVPlayback), and is being removed from the stage in
between loadings - not just for a split second but for significant
lengths of time. I had imagined it would count as a new component
each time, but it seems this is not the case, despite it tracing as
a new instantiation of the parent MC each time.
