Additional Information

DivX files

DivX is the name of a revolutionary new video codec

	which is based on the new MPEG-4 compression
	standard for video. Whether DivX files play correctly on
	your player or not depends on the preparation and
	production of the audio and video files, the codecs and
	the type of recording equipment used, as well as on your
	computer’s parameters. It is therefore possible that you
EN	cannot play a DivX file or that part or all of it is
	defective. It also sometimes happens that you can play
	the images (video) but not the sound (audio).
	DivX disc compatibility with this player is limited as
	follows: • The maximum resolution of the DivX file is
	below 720x576 (W x H) pixels. • DivX filenames should
	not exceed 56 characters. • If the video and audio
	structure of the recorded file is not interleaved, either
	video or audio is outputted. • If the file is recorded with
	GMC, the unit supports only 1-point GMC. GMC is the
	acronym for Global Motion Compensation. It is an
	encoding tool specified in the MPEG4 standard. Some
	MPEG4 encoders, like DivX or XviD, have this option.
	There are different levels of GMC encoding, usually
	called 1-point, 2-point, or 3-point GMC.

•WMA filenames should not exceed 8 characters, and should end with the “.wma” extension.

General name format:Title.wma.When composing your title ensure that you use 8 characters or less, have no spaces in the name, and avoid the use of special characters including (., /, \, =, +).• The total number of files on a disc should be less than 999.

JPEG files

CD-R and CD-RW with JPEG files. Certain JPEG files, including progressive JPEG files, cannot be read by this player.

The total number of files and folders on the disc should be less than 650. Make sure that files have the “.jpg” extension. Files without the “.jpg” extension cannot be read by the player, even though the files are shown as JPEG images on your computer.

Kodak Picture CDs

Sound Enhancement Systems

This player is equipped with several built-in sound enhancement systems.

mp3 files

CD-R and CD-RW discs containing audio files in mp3 format.With regard to CD-R mp3 discs, please follow all the recommendations for CD-R above, along with the comments below:

•Your mp3 files should be ISO 9660 or JOLIET format. ISO 9660 format and Joliet mp3 files are compatible with Microsoft DOS and Windows, as well as with Apple Mac. These two formats are the most widely used. • mp3 filenames should not exceed 8 characters and should end with the “.mp3” extension. General name format: Title.mp3.When composing your title ensure that you use 10 characters or less, have no spaces in the name, and avoid the use of special characters including (. , / , \ , = ,+).• The total number of files on a disc should be less than 400.• Use a decompression transfer rate of at least 128 kB/sec (kilobytes/second) when recording mp3 files. Sound quality with mp3 files basically depends on the rate of compression/decompression you choose. Obtaining audio CD quality sound requires an analogue/digital sampling rate, that is conversion to mp3 format, of at least 128 kB/sec and up to 160 kB/sec. Choosing higher rates, such as 192 kB/sec or more, only rarely produces even better sound quality. Conversely, files with sampling rates below 128 kB/sec will not play properly. • Do not try recording copyright-protected mp3 files.“Securized” files are encrypted and code-protected to prevent illegal copying.You must not copy such files.

Important:The above recommendations cannot be taken as a guarantee that the DVD player will play mp3 recordings, or as an assurance of sound quality. You should note that certain technologies and methods for mp3 file recording on CD-Rs prevent optimal playback of these files on your DVD player (i.e. degraded sound quality and even, in some cases, inability of the player to read the file).

WMA (Windows Media Audio) files

CD-R with WMA files.

D I G I T A L Dolby Pro Logic II

The Pro Logic II mode uses the built-in circuit to steer the Left, Centre, Right and Surround left and right channel audio signals and uses all five speakers to play both stereo and Dolby Pro Logic programme source, such as TV and VCR. Dolby Pro Logic II includes Dolby Pro Logic II Movie, Dolby Pro Logic II Music and Dolby Pro Logic Emulation.

You can use this mode to suit any stereo programme source to enjoy multi-channel sound experience.

Dolby Digital

The Dolby Digital mode lets you enjoy full digital surround from software processed in the Dolby Digital format. Dolby Digital provides better sound quality and a more powerful presence than conventional Dolby Surround.

This unit is equipped with a Dolby Digital 5.1 channel so that you can enjoy enhanced full digital surround sound. Differing from Dolby Pro Logic in that only four channels (Front Left, Front Right, Centre and Rear) are used, the new system provides stereo separation of the rear speakers (Rear-Right, Rear- Left). Adding the subwoofer channel for bass sounds (counted as 0.1 channel) to the 5 channels provides

5.1channels (or 6 Channels) that bring you the most sophisticated Dolby Digital sound enjoyment.

Digital Theater Systems (DTS)

DTS is a digital surround system which delivers six channels of master-quality, 20-bit audio. It offers five full-range channels plus a special low frequency effect (LFE) channel for subwoofer, resulting in what is commonly known as 5.1 channels. It can be applied with existing 5.1 speaker configurations. DTS is available in DVD and CD mode.
