+ NTSC handling needs tightening up - sdl:NTSC is the only valid
+ constructor for NTSC playback at the moment.
On 1/10/2004, Dan Dennedy ran the dv1394d/docs/testing.txt against
mlt albino and miracle.
-Not Implemented/Completely Broken

+General
------------------------------------------------------------------------------
-NLS
-UADD {offline unit} -- to be supported?
+Server side error checks and related response error codes are not stringently enforced.
+
+Not Implemented
+------------------------------------------------------------------------------
+NLS
+INSERT
+MOVE
+REMOVE
+USET points=ignore
Incorrect Behaviour
STOP does not play the test card (white silence) (=pause)
USTA when stopped reports "paused"
REW when stopped does not rewind to the beginning of the clip.
+CLEAN removes all clips (as opposed to leaving the currently playing one)
Different Intentional Behaviour

STOP does not terminate audio/video output
