DVD-R
• Available disc specifications: VIDEO mode only.
• Reusability: Disc can be used only once. Recordings cannot be edited or deleted.
• Finalization: Once finalized, additional recordings cannot be made.
• Compatibility: A finalized DVD-R can be played back on most DVD devices.
DVD-R discs recorded in VIDEO mode offer the best compatibility with external
DVD devices.
DVD-R DL
Dual-layered discs allow writing up to 80% more data (2.6 GB) on a single
recording side according to DVD Forum specifications. Dual layered discs have two
recording layers on a single recording side. The camcorder will record on the first
layer until it is full and then continue on the second layer (as a separate scene).
• Available disc specifications: VIDEO mode only.
• Reusability: Disc can be used only once. Recordings cannot be edited or deleted.
• Finalization: Once finalized, additional recordings cannot be made. To finalize a
dual layered disc the camcorder has to process both layers. Therefore, and
depending on the amount of free space on the disc, this process may be lengthy.
• Compatibility: A finalized DVD-R DL can only be played back on DVD devices
compatible with dual layered discs.
• During the playback of a recording spanning
both layers, you may notice a brief stop at the
point where the camcorder switches from Layer 1
to Layer 2.
DVD-RW
• Available disc specifications: VIDEO mode or VR mode.
[VIDEO]: Offers a higher compatibility with external DVD devices. However, correct
playback cannot be guaranteed with all external DVD devices.
[VR]: Offers easy editing of the recordings with the camcorder.
• Reusability: Recordings can be deleted or the disc can be initialized in order to use
it multiple times or to change the disc specification. Note that initializing a disc will
erase all the recordings on the disc.
• Finalization: Even after a DVD-RW disc is finalized, additional recordings can be
made. The way to do it depends on the disc specification used.
[VIDEO]: You will need to unfinalize the disc first.
[VR]: You can record additional scenes even without unfinalizing the disc.
• Compatibility: The compatibility of the disc depends on the disc specification used.
[VIDEO]: A finalized DVD-RW in VIDEO mode can be played back on most DVD
devices.
[VR]: A DVD-RW in VR mode can only be played back on DVD devices
compatible with VR mode.
