About DVD *7 About MP3 file format MP3 files are audio data compressed in MPEG1 Audio layer 3 file format. "MP3 files" have ".mp3" as extensions. (Some files that have ".mp3" extensions or files that have not been recorded in MP3 format will produce noise or cannot be played.) Æ Playing MP3 discs • Some MP3 files are not played in the order they were recorded. • The maximum number of layers which can be recognized, including files and folders, is 8. • The multi-session discs cannot be played. • It is recommended to record data at a lower speed as data recorded at fast speed can produce noise and may not be able to be played. • The more folders there are, the longer the reading time. • Depending on the folder tree, reading MP3 files can take time. • Folder or track (file) names are limited to 8 characters. Folder or track (file) names that go over 8 characters will be abbreviated. (Certain letters or symbols in folder names or title name may not be displayed.) • The playing time may not be correctly displayed during MP3 file playback. Æ The following files cannot be played on this Recorder. • Discs that have more than 257 folders or 1,000 files. • When both Audio CD format and MP3 files format are recorded on a disc.

Erasure also allows the recording time to be increased. • When a disc has been recorded in the Video mode, additional recording is possible until the disc is full. The recording time does not increase*8 even if titles are erased, but if the disc is initialized (see pages 14 and 84) full recording time is possible. *8 Recording time can only be increased when the last title is erased (titles cannot be erased after a disc has been finalized). DVD-R Discs • DVD-R discs can only be recorded in the Video mode. • Although additional recordings can be made until the disc is full, disc space does not increase even if titles are erased (because erasure here refers only to making the titles not visible). • Although these discs can be played back with other DVD players once they have been finalized, the discs can no longer be recorded or erased after they have been finalized. • Discs can be additionally recorded and edited with this Recorder only until they are finalized. 11
