Use this method to save the decoded closed captioning data coming from LEAD MPEG2 decoder. Closed captioning data might be embedded inside MPEG2 Video Elementary stream. If so, then the convert object is able to decode this data and write it to SRT format using this method, were the closed captioning text and time are saved. For more information, refr to http://en.wikipedia.org/wiki/SubRip. Also the convert object can save the closed captioning data as text.
By default this method saves the data as SRT file; but if ClosedCaptioningFlags.Text is specified, the output will be as pure text file.
