**************************************************************************
*  Einschraenkungen vorhanden. Unterstuetzt nicht gesamten MPEG/SYSTEMS  *
*  Standard. Haelt sich i.d.R. an den CSPF-Werten, zusaetzlich (noch)    *
*  nur fuer ein Audio- und/oder ein Video- Stream. Evtl. erweiterbar.    *
**************************************************************************
*  Restrictions apply. Will not support the whole MPEG/SYSTEM Standard.  *
*  Basically, will generate Constrained System Parameter Files.		 *
*  Mixes only one audio and/or one video stream. Might be expanded.	 *
