Streaming RealPlayer Content From an Access Database (not sending correct headers?)

I've almost got this working, expect that I'm not sending the correct "Content-type" header to the RealPlayer player. I've followed a tutorial from the O'Reilly network ( http://www.onlamp.com/pub/a/php/2000/09/15/php_mysql.html?page=1 ), and modified it for an Access database, and RealPlayer content. I click on a hyperlink in the table, thus initilizing the "download" script. RealPlayer opens up, then says it can't identify what I'm trying to play and will try and find a plugin for it, then the search for the plugin fails. The current content type header reads header("Content-type: application/vnd.rn-realmedia"); Does anybody have any clue what type RealPlayer might identify? Here's my code for the download script. ================================= if ($id) { include "talks.php.inc"; // This is the include file, I just named it differently from the tutorial $sql = "SELECT * FROM tblTalks WHERE TalksID=$id"; $cursor = odbc_exec($db_talks, $sql); $data = odbc_result($cursor, "fldBinData"); $name = odbc_result($cursor, "fldFileName"); $title = odbc_result($cursor, "fldTitle"); $summery = odbc_result($cursor, "fldSummery"); header("Content-type: application/vnd.rn-realmedia"); header("Content-Disposition: stream; filename=$name"); header("Content-Description: Speeches from Barry"); echo $data; } ================================ Here is the source for the include file ================================ /* talks.php.inc */ /* Note that I left out the "or die" parts out (in the $db_talks and $sql), they were very long, and would make the code unreadable here */ $db_talks = odbc_connect("TalksDatabase", root, ''); function make_query($query) { global $db_talks; $sql = odbc_exec($db_talks, $query); return $sql; } ================================ Thanks for any help you peeps can give me.
