increase even if titles are deleted.
¾ Available recording space on DVD-RW (DVD-Video format) or
+RW increases only when the last recorded title is deleted. It
does not increase if other titles are deleted.
¾ If you record or edit about 200 times or more, the remaining
capacity of DVD-R, DVD-R DL, +R, and +R DL is reduced and
then recording or editing may be disabled (for the second layer
on DVD-R DL and +R DL, this happens after about 60 times).

elapsed time displayed is less.
(Only when recording in NTSC)
¾ The displayed recording/play time is converted from the
number of frames at 29.97 frames (equal to 0.999 seconds) to
one second. There will be a slight difference between the time
