• This unit is compatible with discs recorded in the standard
DVD-Video format.
• Note that discs not finalized (processed to enable to play on
playback-only DVD players) cannot be played on this DVD
player.
• Some discs may not play back, depending on the recording

About MP3/WMA/AAC/FLAC

CAUTION
Except for private use, duplicating audio data (including
MP3/WMA/AAC/FLAC data) or distributing, transferring,
or copying it, whether for free or for a fee, without
permission of the copyright holder is strictly prohibited
by the Copyright Act and by international treaty.
What is MP3?
MP3, whose official name is "MPEG Audio Layer 3," is a compression
standard prescribed by the ISO, the International Standardisation
Organisation and MPEG which is a joint activity institution of the IEC.
MP3 files contain compressed audio data. MP3 encoding is capable
of compressing audio data at extremely high ratios, reducing the size
of music files to as much as one-tenth their original size. This is
achieved while still maintaining near CD quality. The MP3 format
realizes such high compression ratios by eliminating the sounds that
are either inaudible to the human ear or masked by other sounds.
What is WMA?
WMA, or "Windows Media™ Audio," is compressed audio data.
WMA is similar to MP3 audio data.
What is AAC?
AAC is the abbreviation for "Advanced Audio Coding, " and is a basic
format of audio compression used by MPEG2 or MPEG4.
What is FLAC?
FLAC (Free Lossless Audio Codec) is an audio file codec for lossless
compression, developed and offered as open source software.
Codecs with lossy compression forms, such as MP3 and AAC, reduce
part of the data to improve compression efficiency.
However, FLAC can reconstruct compressed data to be an identical
copy of the original data by performing lossless compression. The
compression ratio of FLAC is about 50%.
Method for creating MP3/WMA/AAC/FLAC (USB Flash drive) files
Audio data is compressed using software with MP3/WMA/AAC/FLAC
(USB Flash drive) codecs. For details on creating MP3/WMA/AAC/
FLAC (USB Flash drive) files, refer to the user's manual for that
software.
MP3/WMA/AAC/FLAC (USB Flash drive) files that are playable on this
device have the file extensions.
MP3: "mp3"
WMA: "wma"
AAC: "m4a"
FLAC: "flac"/"fla"
WMA is not supported for the following files, Windows Media Audio
Professional, Windows Media Audio 10 std or Windows Media Audio
10 Pro Lossless.
There are many different versions of the AAC format. Confirm that the
software being used conforms to the acceptable formats listed
above. It's possible that the format may be unplayable even though
the extension is valid.
Playback of AAC files encoded by iTunes is supported.
