Note that speeds shown in the table are an
approximate of the maximum dubbing speed.
*1
Maximum recording speed of this recorder.
*2
When dubbing to DVD+Rs, the dubbing speed is
x1-speed.
Notes
• High-speed Dubbing is not available for the following
titles:
– Titles recorded in HQ+.
– Titles that contain both main and sub sounds (except
DVD-RWs (VR mode)).
– Titles recorded in mixed picture size (4:3 and 16:9
etc.), (except DVD-RWs (VR mode)).
– Titles recorded in SLP (DVD+RW/DVD+R only).
• When dubbed to a DVD-RW (Video mode)/
DVD+RW/DVD+R/DVD-R, erased pictures may
remain on the disc.
Rec Mode Conversion Dubbing
n / / / /
Allows you to dub from the HDD to a DVD or vice
versa, in a dubbing mode that differs from the
original recordings. For example, when you dub
an HQ title (data size is large) in SP mode, you can
reduce the data size, saving more titles using less
space.
Select a mode different from the original recording
in “Dub Mode” in the steps of “Dubbing a Single
Title (Title Dub)” (page 74) or “Dubbing Multiple
Titles (Dub Selected Titles)” (page 75).
When an HQ or HQ+ title is converted to another
mode, the recorder automatically assigns an
appropriate bit rate, thus retaining the original
picture quality as much as possible (“Dynamic
VBR Dubbing”).
◆About “VBR”
VBR (Variable Bit Rate) is an effective method of
allocating a suitable bit amount per second. Fine
detail pictures or dynamically moving pictures are
assigned a larger amount, while static pictures are
assigned less, for optimum picture quality.
z Hint
When you dub an edited title using the Rec Mode
Conversion Dubbing method, pauses between scenes are
smoothed out.
Note
The picture quality will not improve even if a title is
converted to a recording mode of better picture quality.
Dubbing restriction
Some DVD VIDEOs or TV programmes contain
copy protection signals such as “Copy-Never” or
“Copy-Once.” You cannot record such contents on
this recorder (only a grey, blank screen will be
recorded). Be especially careful when dubbing on
a non-rewritable DVD such as a DVD-R.
