DESCRIPTION    [Toc]    [Back]

     In	some circumstances an application may not be allowed to	read or	edit a
     movie while appending frames to its tracks; this is currently the case
     for MPEG-1	movies.	 In general, mvIsAppendOnly should be called after a
     movie is created to determine whether or not reading and editing calls
     are allowed.  mvIsAppendOnly returns DM_TRUE if the movie is append-only
     and DM_FALSE if it	is not.
