About DVD-R and DVD-RW disc
How are DVD-R and DVD-RW discs different?
The essential difference between DVD-R and DVD-RW
is that DVD-R is a record-once medium, while DVD-RW
is a re-recordable/erasable medium. You can re-record/
erase a DVD-RW disc approximately 1,000 times.
Can I play my recordable discs in a regular DVD
player?
Generally, DVD-R discs and DVD-RW discs recorded in
Video mode are playable in a regular DVD player, but
they must be ‘finalized’ first. This process fixes the con-
tents of the disc to make them readable to other DVD
players as DVD-Video discs.
DVD-RW discs recorded in VR (Video Recording) mode
are playable in some players.
This indicates a product feature that is capa-
ble of playing DVD-RW discs recorded with
Video Recording format.
What are ‘recording modes’?
There are two recording modes available using this
recorder: VR mode and Video mode. When recording to
a DVD-R disc, recordings are always in Video mode.
DVD-RW discs can be formatted for VR mode recording
or Video mode recording.

• 4 different picture quality/recording time settings avail-

ote
DVD-Video Format (Video mode) is a new format for
recording on DVD-R/RW and DVD+R/RW discs that
was approved by the DVD Forum in 2000. You may
therefore experience problems playing recordable DVD
discs in some players. Symptoms include video arti-
facts, audio and/or video dropouts and playback sud-
denly stopping.
Our company cannot take responsibility for problems
playing discs recorded on this recorder in other players.
Is editing a DVD like editing a video tape?
No. When you edit a video tape you need one video
deck to play the original tape and another to record the
edits. With DVD, you edit by making a ‘Playlist’ of what
to play and when to play it. On playback, the recorder
plays the disc according to the Playlist.
About word ‘Original’ and ‘Playlist’
Throughout this manual, you will often see the words
Original and Playlist to refer to the actual content and
the edited version.
• Original: content refers to what’s actually recorded
on the disc.
• Playlist: content refers to the edited version of the
disc — how the Original content is to be played.
