DVD control limitations
The controls on certain DVD discs may be prohibited or disabled. The PDR-155 will display an
icon ( ) that means a function is “prohibited by the disc” if you try to execute such a function.
On discs that enable interactive controls from the menu or during playback, certain functions
(such as repeat play or programming) may not be available. In these cases, the PDR-155 will dis-
play an icon ( ) that means the function is “prohibited by the player.”
About video CDs
This DVD AV Controller supports Video CDs with or without PBC (Version 2.0). (PBC is an abbre-
viation for Playback Control.)
•
Video CDs without PBC (Version 1.1)
Video CDs that do not utilize PBC allow you to play sound and movies on the PDR-155 using the
same operations you would use to play an audio CD.
•
Video CDs with PBC (Version 2.0)
Video CDs that utilize PBC also allow you to play sound and movies on the PDR-155. In addition,
these discs enable you to use interactive software and search functions from a menu displayed on
the TV screen (Menu Playback). Some of the functions described in this Instruction Manual may
not work with some discs.
MP3 compatibility information
• The CD-ROM must be ISO9660-compatible.
• Files should be in the MPEG1 Audio Layer 3 format, 44.1 or 48 kHz, fixed bit rate. Incompatible
files will not play and the system will display “UNPLAYABLE.”
• The PDR-155 plays only tracks that use the file extension “.mp3” or “.MP3”.
• Use CD-R or CD-RW media to record your MP3 files.
• The disc must be finalized to play properly.
•Audio encoded at 128kbps should sound nearly as good as standard audio CDs. Although the
PDR-155 will play MP3 tracks encoded at lower bit rates, the audio quality is noticeably worse.
• Only the first eight characters of a folder or track name (excluding the “.mp3” extension) are dis-
played.
• The PDR-155 can recognize a maximum of 250 folders and 250 tracks. Folders and tracks in
excess of 250 will not play.
• The PDR-155 is not compatible with variable bit rate (VBR) files. Be sure to create MP3
CDs with a fixed bit rate.
• The PDR-155 is not compatible with multi-session discs. If you try to play a multi-ses-
sion disc, the PDR-155 will play only the first session.
