Probleme Flash und PHP-Mysql

Hallo habe bei meinem Projekt folgendes Problem,
möchte gerne über PHP-mysql eine Playliste erstellen, die mein Player abspielen soll, klappt leider nicht, kann mir da einer weiter helfen, mir sagen wo mein Problem ist und mir helfen das es klappt

meine PHP "player.php"

PHP-Code:

<?php
include("dbase.php");

$result=mysql_query("SELECT * FROM `music_users` WHERE user='$username'");


header("content-type:text/xml;charset=utf-8");
echo "<playlist version=\"1\" encoding=\"UTF-8\">\n";
echo "<player showDisplay=\"yes\" showPlaylist=\"yes\" autoStart=\"yes\">\n";


while($row = mysql_fetch_row($result)) {

echo"<song path=\"$username/$row[3]\" title=\"$row[2]\" >\n";
}
echo "</player>\n";
?>

hier der code fürs Flash

verstehe nicht warum es nicht funktioniert, wenn ich die php einzel aufrufe sieht sie aus wie die xml datei, wenn ich eine xml datei und den namen nehme dann klappt es.
Wenn 1000 User da wären, kann ich ja nicht 1000 xml dateien schreiben, es muß doch ne möglichkeit geben.
Kenne mich leider zu wenig aus mit flash, habe dieses zusammengewürfelt, bitte helft mir.

Vielen Dank im vorraus
