They quite a long list of limitations, and gremlins, however, the important bit
is this section:

Note: To use variable frame rates, stream the video using either progressive 
downloading or Flash Media Server. When you import video files using either of 
these methods, the FLV or F4V files are self-contained and run at a frame rate 
separate from that of all other timeline frame rates included in the SWF file.

So, if I were to point you at a compilable .sc that had 'thisland.swf' and
and another .flv playing at the same time, 'embedded' within it, I'd prove
my point ( albeit rather raucously ), and you'd be happy? ;o)

flvs are designed for being streamed Pablo, not embedded.

It is also possible to have two swfs embedded in another swf, and slow the
frame rate of both of them at the same time with swfc/action script.  It
does not work brilliantly - Adobe use the phrase inconsistent - but it is
possible.

As mentioned previously, why would you need to use flv-player, when this,

[ see the Video section ]

does it for you?

That depends!
