Many thanks for your reply, Chris, and sorry for not having replied 
before (I was busy with other things).

I knew that this is a Flash player and that Adobe >8 contains a built-in 
Flash player. This is why I wrote to the list to show how this is 
possible in PDF and not in SWF (read below).

Adobe explains that when embedding videos both SWF file and embedded 
video clip must have the same frame rate, otherwise video playback would 
be inconsistent 
(http://help.adobe.com/en_US/Flash/10.0_UsingFlash/WSBDABD69F-D146-4e5c-9340-BF717A10426C.html).

I love to have a .sc file having a .flv file embedded into a SWF file, 
with different frame rates. Video should contain sound.

Sorry, but unless I'm wrong, this is impossible due to the limitations 
of the SWF format itself. Or at least of the video embedding.

It might be possible to embed the video as binary data (chapter 15 of 
the SWF 10 specification). But I guess this has not been implemented in 
swfc and I don't know how would it be possible to play it with 
http://flv-player.net.

I may be wrong and not getting anything right, but I think this is a 
limit in SWF design itself.

Thanks for your help,


Pablo
