MP3/WMA Play CD-R MP3/WMA discs When playing CD-R/MP3 or WMA discs, please follow all the recommendations for CD-R above, plus the comments below: • Your MP3 or WMA files should be ISO 9660 or JOLIET format. ISO 9660 format and Joliet MP3 or WMA files are compatible with Microsoft's DOS and Windows, and with Apple's Mac. These two formats are the most widely used. • When naming your MP3 or WMA files do not exceed 8 characters, and place ".mp3, .wma" as the file extension. General name format of: Title.mp3. or Title.wma. When composing your title, make sure that you use 8 characters or less, have no spaces in the name, and avoid the use of special characters including • Use a decompression transfer rate of at least 128 Kbps when recording MP3 files. Sound quality with MP3 files basically depends on the rate of compression/decompression you choose. Getting audio CD quality sound requires an analog/digital sampling rate, that is conversion to MP3 format, of at least 128 Kbps and up to 160 Kbps. However, choosing higher rates, like 192 Kbps or more, only rarely give better sound quality. Conversely, files with decompression rates below 128 Kbps will not be played properly. • Use a decompression transfer rate of at least 64Kbps when recording WMA files. Sound quality with WMA files basically depends on the rate of compression/decompression you choose. Getting audio CD quality sound requires an analog/digital sampling rate, that is conversion to WMA format, of at least 64Kbps and up to 192Kbps. Conversely, files with decompression rates below 64Kbps or over 192Kbps will not be played properly. • Do not try recording copyright protected MP3 files. Certain "securized" files are encrypted and code protected to prevent illegal copying. These files are of the following types: Windows MediaTM (registered trade mark of Microsoft Inc) and SDMITM (registered trade mark of The SDMI Foundation). You cannot 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 (degraded sound quality and in some cases, inability of the player to read the files). • This unit can play a maximum of 500 files and 300 folders per disc. 34 Program Play & Random Play Program Play (CD/MP3/WMA) 1 Press the MODE button. 2 Use the LEFT/RIGHT buttons to select PROGRAM.
