The displayed time of this unit is different from
the actual recording time or MP3 recording time.
Times shown may disagree with actual times.
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
1 second. There will be a slight difference between the time
displayed and the actual elapsed time (e.g., actual 1 hour
elapsed time may display as approximately 59 minutes

unit at the same time for about 5 seconds. Remove the disc.
TV screen and video
Television reception worsens after connecting
the unit.
This can occur because the signals are being divided between
the unit and other equipment. It can be solved by using a signal
booster, available from audio-visual suppliers. If it is not solved
by using a signal booster, consult the dealer.
The digital channel information or control panel
does not appear.
Select the length of time (3–10 sec.) that the "On-Screen
Messages" in the Setup menu will be displayed. (
The digital channel information will not appear during playback
or recording.
Analogue broadcasts do not support the digital channel
information.
The control panel is only displayed when connected to a TV
supporting "HDAVI Control 2" or later. (
Some functions of DVB-T do not work.
The unit does not necessarily support all DVB-T functions such
as MHP (Multimedia Home Platform) etc.
New functions introduced by broadcasters cannot be
guaranteed to work.
The grey background does not appear.
Select "On" in "Grey Background" in the Setup menu. (
Screen size is wrong.
Use the television to change the aspect. If your television does
not have that function, set "Progressive" in the Picture menu to
"Off". ( 44)
Check the settings for "TV Aspect" in the Setup menu. (
If you connect an HDMI cable, set "Aspect for 4:3 Video" to
"16:9" in the Setup menu. (
The recorded title's screen size is wrong.
Set "Rec for High Speed Copy" to "On", and set the "Aspect for
Recording" to "4:3". ( 51)
16:9 aspect programmes are recorded in 4:3 aspect in the
following cases.
– [-R] [-R]DL] [-RW‹V›] If you recorded or copied using "EP" or "FR
(recordings 5 hours or longer)" recording mode.
– If you recorded or copied to a +R, +R DL or +RW.
– If you recorded with the "Aspect for Recording" set to "4:3" in
the Setup menu.
When you want to record 16:9 programme in the same
aspect, set "Rec for High Speed Copy" to "On", and set the
"Aspect for Recording" to "16:9". (
By setting "Aspect for Recording" to "Automatic", there is a chance
that the recording will be made using the wrong aspect. Match the
aspect settings to the broadcast when recording. (
It may be possible to adjust the display mode on the TV. Refer to
your television's operating instructions.
