When my movie is played in Internet Explorer, it seems to be set at 12fps, when my movie is 15.

I found a fix

Replace the HTML code with something like this:

<object classid="clsid:D27CDB6E-AE6D-11cf-96B8-444553540000"
codebase="http://download.macromedia.com/pub/shockwave/cabs/flash/swflash.cab#ve
rsion=5,0,0,0" width="256" height="168">
<param name=movie value="jim.swf">
<param name=loop value=1>
<param name=quality value=high>
<param name=scale value=noborder>
<param name=wmode value=transparent>
<param name=bgcolor value=#000000>
<embed src="files/jim.swf" loop=1 quality=high scale=noborder
wmode=transparent bgcolor=#000000 width="256" height="168"
type="application/x-shockwave-flash"
pluginspace="http://www.macromedia.com/shockwave/download/index.cgi?P1_Prod_Vers

</object>
