Compared to the actual 
recorded time, the elapsed time 
displayed is less.
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.
The time recorded on the disc 
and the available time shown 
do not add up.
The play time shown for MP3 
does not agree with the actual 
time.
Times shown may disagree with actual times.
Available recording space on DVD-RW (DVD-Video format) increases only when the last 
recorded title is erased. It does not increase if other titles are erased.
Even if you erase recorded content from the DVD-R or +R, there is no increase in disc space.
More disc space than the actual recording time is used after recording or editing the DVD-R 
or +R 200 times or more.
While searching, the elapsed time may not display correctly.


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.
Status messages do not 
appear.
Select “Automatic” in “Status Messages” in the SETUP menu.

The blue background does not 
appear.
Select “On” in “Blue Background” in the SETUP menu.

The 4:3 aspect ratio picture 
expands left and right.
Screen size is wrong.
Use the television to change the aspect. If your television does not have that function, set 
“Progressive” in the Video menu to “Off”.
Check the settings for “TV Type”, “4:3 TV Settings for DVD-Video” or “4:3 TV Settings for 
DVD-RAM” in the SETUP menu.

There is a lot of after-image 
when playing video.
Change the settings for “Integrated DNR” to “0” or turn “MPEG-DNR” off if it is on.
37
When playing DVD-Video using 
progressive output, one part of 
the picture momentarily 
appears to be doubled up.
Set “Progressive” in the Video menu to “Off”. This problem is caused by the editing method or 
material used on DVD-Video, but should be corrected if you use interlace output.
37
There is no apparent change in 
picture quality when adjusted 
with the Video menu in the on-
screen menus.
The effect is less perceivable with some types of video.
