and the available time shown do
not add up.

does not agree with the actual
time.

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.
Even if you delete recorded content from the DVD-R, DVD-R DL, +R or +R DL, there is no
increase in disc space.
More disc space than the actual recording time is used after recording or editing the DVD-R,
DVD-R DL, +R or +R DL 200 times or more.
While searching, the elapsed time may not display correctly.
Compared to the actual recorded
time, the elapsed time displayed
is less.
(Only when recording in NTSC)
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
displayed and the actual elapsed time (e.g., actual one-hour elapsed time may display as
approximately 59 minutes 56 seconds). This does not affect the recording.
