Otra cosa rara, es que si pruebo los archivos swf por separado desde mi ftp tambien funcionan bien. Es solo al momento de ponerlo en el html. Mi codigo de html es:
<body aLink=#FDE600 link=#FDE600 vLink=#FDE550 leftmargin="0" topmargin="0" marginwidth="0" marginheight="0" bgcolor="#990000" >
<table width="700" border="0" align="center" cellpadding="0" cellspacing="0" background="fondo menu.jpg">
<tr>
<td>
<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000" width="170" height="130" title="Constructora e Inmobiliria">
<param name="movie" value="menu.swf">
<param name="quality" value="high">
<param name="wmode" value="transparent">
<embed src="menu.swf" width="170" height="130" quality="high" type="application/x-shockwave-flash" wmode="transparent"></embed>
</object></td>
