+ *     Not present with Live streams
+ * sgiLiveFeed=True|False
+ *     Denounces if the stream is live or from assets (Canned?)
+ *     Live appears as a little sattelite dish in the web interface of Kasenna
  * sgiFormatName=PARTNER_41_MPEG-4
+ *     The type of stream. One of:
+ *       PARTNER_41_MPEG-4 (RTSP MPEG-4 fully compliant)

+ * sgiWidth=720
