 <para>The ioctls that deal with SPUs (sub picture units) and navigation packets are only
 supported on some MPEG decoders made for DVD playback.
 </para>
+<para>
+These ioctls were also used by V4L2 to control MPEG decoders implemented in V4L2. The use
+of these ioctls for that purpose has been made obsolete and proper V4L2 ioctls or controls
+have been created to replace that functionality.</para>
