ok, questo è il codice per inserilre il .FLV su pagine dinamiche in ASP e supportato da explorer ed firefox:

I due file esterni AC_ActiveX.js + AC_RunActiveContent.js non li posso posare perché sono "Copyright 2006 Adobe Systems, Inc. All rights reserved."
C'è bisogno anche del file "Clear_Skin_1.swf" e "FLVPlayer_Progressive.swf"
Questi 4 file vengono generati automaticamente da Dremwaver 8.0.2 facendo come già precedentemente indicato.
