Do DVD+RW discs need to be finalized?
No. Every time a DVD+RW disc is ejected, either from a DVD+R/+RW drive in a PC or from a DVD+R/+RW video recorder, it automatically contains the needed information for the disc to be read in a normal DVD-Video player or DVD-ROM drive. There is no need to perform a time-consuming finalization process on the disc, as is required for all other rewritable DVD formats, and for CD-RW. Likewise, there is no such thing as unfinalizing a DVD+RW disc: it is always possible to make modifications or add new contents to a disc without performing some special procedure in advance.
Unlike competing formats, a DVD+RW disc does not require long finalization times. A DVD+RW disc recorded on a DVD+RW video recorder can immediately be played on a DVD-Video player, without the need for finalization. A disc can be edited, or new recordings can be added, without needing to erase completely the existing video recording.
