Dubbing (HDD y DVD) Note that speeds shown in the table are an approximate of the maximum dubbing speed.

Notes • High-speed Dubbing is not available for the following titles: - Titles recorded in HQ+. - Titles that contain both stereo or monaural audio tracks (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 HDD n +RW / -RWVR / -RWVideo / +R / -R 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. • Variable bit rate (adopted • Fixed bit rate for this recorder) Average distribution rate Average distribution rate Wasted bits More bits are required 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 programs contain copy protection signals such as "Copy-Never" or "Copy-Once." You cannot record such contents on this recorder (only a gray, blank screen will be recorded). Be especially careful when dubbing on a non-rewritable DVD such as a DVD-R.
