Getting around the Firefox wmv streaming problem

[SubFighterMax]

This code seems to work just fine when I view the page in IE. But when I view it in Firefox, the embedded WMP just says "Ready" and the play button does nothing.

 

<OBJECT ID='NSPlay' WIDTH='400' HEIGHT='300' CLASSID='CLSID:22D6F312-B0F6-11D0-94AB-0080C74C7E95' STANDBY='Loading Windows Media Player components...' TYPE='application/x-oleobject'>
<PARAM NAME='FileName' VALUE='video_play_2416.wmv'>
<PARAM NAME='AutoSize' VALUE='0'>
<PARAM name='AutoStart' VALUE='1'>
<PARAM name='ShowControls' VALUE='1'>
<PARAM name='ShowDisplay' VALUE='0'>
<param name='ShowStatusBar' value='1'>
<EMBED TYPE='application/x-mplayer2' SRC='video_play_2416.wmv' NAME='NSPlay' WIDTH='400' HEIGHT='300' AutoSize='1' AutoStart='1' ShowControls='1' ShowDisplay='0' ShowStatusBar='1'></EMBED>
</OBJECT>

 

video_play_2416.wmv converts to video_get.php?id=2416 in my .htaccess. Here is the basic code for the video_get.php:

 

<?
header("Content-Type: video/x-ms-wmv");
header("Accept-Ranges: bytes");
header("Content-Length: ".filesize("video_$id.wmv"));
header("Content-Disposition: attachment; filename=\"video_$id.wmv\"");
readfile("video_$id.wmv");
?>

 

It works fine in Firefox if I link it directly to the wmv, but doesn't work if it has to go through the script. Works fine both ways in IE. I Google'd around and all I have found is that other people seem to be having the same problem. Does anyone have a way to make it work for Firefox?
