NTSC video cassette playback
When using a pre-recorded NTSC video cassette tape, the connected
TV set must be compatible with a 60Hz vertical frequency (sometimes
known as a PAL 60Hz feature). Otherwise the on-screen picture will be
affected by vertical rolling. Even if your VCR set is capable of processing
NTSC video signals, the picture may be shortened vertically (appear-
ance of black bars at the top and at the bottom of the TV screen). The
dubbing of a NTSC video cassette tape to a standard PAL VCR is not
possible.

Read this before recording on disc
Types of disc
You can use DVD-RW and DVD-R discs to record video.
DVD-RW discs
• Ver 1.1 and later discs can be formatted for recording in either of the
two modes: the VR mode or the Video mode. Ver.1.0 discs can only
be formatted for recording in the VR mode.
• High quality images and sound can be repeatedly recorded about
1,000 times.
• A disc formatted in the VR mode can have as many as 99 original
titles and playlist titles each. Discs formatted in the Video mode can
have up to 99 original titles.
DVD-R discs
• Discs can only be recorded in the Video mode.
• Discs can be recorded only once.
• Up to 99 titles can be created.
For more information on recording format, see “Recording for-
mat” (page 10).
Notes on recording in the Video mode
• The Video mode cannot be selected for Ver. 1.0 DVD-RW discs.
• The remaining available area on the disc decreases as recording
progresses. Additional contents can be recorded in the remaining
time area, but it cannot be overwritten into the recorded area.
• To format a new DVD-RW in the Video mode, set the automatic for-
mat feature to the Video mode. (See page 23.)
Recording modes
There are 4 modes for recording on disc. Recording time and quality
vary according to mode.
• Recording time above is based on a 4.7GB disc.
Since DVD recording is performed using VBR (Variable Bit Rate), re-
cording time varies according to the recorded content.
To know the correct recording time, stop recording and check the me-
dia information. (See page 32.)
This section explains things you must
know to record onto a disc. Read it
before attempting to record.
NOTES:
Recording time can change for the
following reasons.
• When image quality is poor as dur-
ing poor TV reception.
• When recording on a disc that has
been edited before.
• When the video is followed with re-
cordings of still images or just au-
dio.
NOTE:
Should a power failure occur or
should the AC cord plug be discon-
nected while recording, editing, ini-
tializing, finalising or any other func-
tion, the program being recorded will
be lost or the disc may not be play-
able. Manufacturer can not guaran-
tee against loss of program or disc
should this occur. To start recording
again, re-format the disc or use a new
disc and follow the instruction on re-
cording.
