*   trackname   :   filename | drive letter
*   tracklist   :   filename+
*
*      -track      A track list if a list of tracks that the user wants
*                  to play.  It overides any play list that may already be stored
*                  for the current cd.
*
*      -play       Start playing the current play list.  If -play is not specified
*                  CD Player seeks to the first track in the play list.
*
*
*   On Windows NT the format of [file] is:
*       d:\track(nn).cda
*
*   where d: is the drive letter of the cdrom that you want to play
*   and \track(nn) is the track number that you want to play.

* -1 iff the caller passed FALSE for the fQuiet parameter and the message box was
* actually displayed.  This should only occur when the user trys to start a new
