+What:  dv1394 driver (CONFIG_IEEE1394_DV1394)
+When:  June 2007
+Why:   Replaced by raw1394 + userspace libraries, notably libiec61883.  This
+       shift of application support has been indicated on www.linux1394.org
+       and developers' mailinglists for quite some time.  Major applications
+       have been converted, with the exception of ffmpeg and hence xine.
+       Piped output of dvgrab2 is a partial equivalent to dv1394.

-         This driver allows you to transmit and receive DV (digital video)

-         The user-space API for dv1394 is documented in dv1394.h.

-         To compile this driver as a module, say M here: the
-         module will be called dv1394.
+         The dv1394 driver will be removed from Linux in a future release.
+         Its functionality is now provided by raw1394 together with libraries
