ma...
l'hai letta la mia risposta sopra?
prova a mettere il tag embed (che serve per il mac...).
hai messo solo l'object:
<td height="292">
<div align="center"><object width="100%" height="100%" classid="clsid27CDB6E-AE6D-11cf-96B8-444553540000" codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#4,0,2,0">
<param name="SRC" value="intro.swf">
<param name="QUALITY" value="high">
<param name="SCALE" value="exactfit">
</object>
</div>
