It is a criminal offense, under applicable copyright laws, to make unauthorized copies of copyright-protected material, including computer programs, films, broadcasts, and sound recordings. Observe the following guidelines when burning a CD or DVD: Before burning a disc, save and close any open files and close all programs. A CD-R or DVD-R is usually best for burning audio files because after the information is copied, it cannot be changed. Because some home and car stereos will not play CD-RWs, use CD-Rs to burn music CDs. A CD-RW or DVD-RW is generally best for burning data files or for testing audio or video recordings before you burn them to a CD or DVD that cannot be changed. DVD players used in home systems usually do not support all DVD formats. Refer to the user guide that came with your DVD player for a list of supported formats. An MP3 file uses less space than other music file formats, and the process for creating an MP3 disc is the same as the process for creating a data file. MP3 files can be played only on MP3 players or on computers with MP3 software installed. To burn a CD or DVD, follow these steps: 1. Select Start > All Programs, and then select the name of the software you want to use. Select the kind of CD or DVD you want to create--data, audio, or video. Right-click Start, click Explore, and navigate to the folder where the source files are stored. Open the folder, and then drag the files to the drive that contains the blank optical disc. Initiate the burning process as directed by the program you have selected. For specific instructions, refer to the software manufacturer's instructions, which may be provided with the software, on disc, or on the manufacturer's Web site.
