- * Es koennen mehrere Varianten beim Abspielen verwendet werden.
- *
- * Abspielen eines Titels
- * abspielenMitParameternUndRueckmeldung(urlStr, null, null, 1)
- *
- * Abspielen eines Titels mit Rueckmeldung (z.B. fuer Playlisten)
- * abspielenMitParameternUndRueckmeldung(urlStr, null, meldeUrlStr, 1)
- *
- * Abspielen mit Parametern
- * abspielenMitParameternUndRueckmeldung(urlStr, parameter, null, 1)

- * Abspielen mit Parametern und Rueckmeldung
- * abspielenMitParameternUndRueckmeldung(urlStr, parameter, meldeUrlStr, 1)
- *
- * Token wird zur Zeit nicht genutzt, hier kann einfach eine beliebige
- * Zahl uebergeben werden.
- *
- * Die drei Parameter t, p, r werden als Query im URL erwartet. Beispiele:
- * t = titel

- * r = url fuer rueckmeldung
