In addition, it may not be available when playing streaming or progressively downloaded
media.
To select speeds between the play speed marks,
clear the Snap slider to common speeds check box.
The timecode indicator is only active when
playing files in Windows Media Format that include Society of
Motion Picture and Television Engineers (SMPTE) timecode
information. The timecode indicator displays the progress of the
file in hours, minutes, seconds, and frames (hh:mm:ss:ff).
