My experimentation says the answer to that one, no.  Separate containers,
and you can have separate swfs at separate frame rates ( with the proviso
given previously, that it you if meddle with an individual video's frame
rate, it destroys the sync with any embedded sound )

You can certainly do that with swfc.  No problem at all.

There is no shortcoming at all Pablo. You *CAN* embed multiple videos,
both swf and flv inside another swf, or swfs.  After all, that is what
a sprite actually is, now isn't it?

.. anything that does, can be done with swfc.

If you'd scanned the README for the above program, you have noticed that
this only works because Adobe have embedded a Flash component in Adobe
Reader 9 and upwards.

But it is.  You can even have them all playing at the same time.

Would you care for a link to a flash file, within a flash file, within a
flv, within a...? ;o)
