• When I insert a data disc in the burner drive and select Edit Disc, the program prompts this message: "Please insert a disc and make sure the disc is editable."
• I created a data disc with the ISO 9660 file system. Why did parts of file names and folder names on the disc changed to underscore '_' characters?
• Why doesn't the write speed combo box enumerate all the available speeds for my burner device?
• I compiled 4651MB of data files to create a data DVD, which has not exceeded the DVD disc capacity of 4.7GB. However, when I tried to burn the disc, a message is displayed saying that the disc does not have enough space.
• I added .WMA files to create an audio disc but the program does not accept these files.
• The program displays a disc error or disc type error message when I try to view the disc information. When I try to create a data disc, the program shows the following message: "The program cannot perform the task you selected using the current disc. Please check your disc and try again."
• When burning a data disc, the error message "Failed to open file" is displayed and the burning process is aborted.
• I am having problems burning discs with an external burner drive that uses a USB 2.0 connection.
• I am using an IDE burner drive enclosed in a USB 2.0 external box. When I try to burn discs, the program does not respond for a long time during the burning process.
• How do I check if a disc is compatible with my burner?

If the disc is closed or write-protected, it cannot be edited.

ISO 9660 file names and folder names are limited to characters A-Z, numbers 0-9, and an underscore '_'. Other special characters are not allowed, and they will be replaced with an underscore '_'. To retain special characters in file names and folder names, select the Joliet option in the Burn Disc dialog box.

If you find that the program does not list all available write speeds for your burner device, contact Ulead technical support. Provide us with the following information: device vendor name, model number, and write speeds that your burner device supports.

Aside from the data files, additional information will be written to the disc: lead-in area (storing the table of contents); lead-out area (marking the end of a burning session); and file system information. The actual size to be burned to disc may therefore be larger than the data size shown in the Disc-space Meter or the Burn Disc dialog box.

Check and make sure that the .WMA files are not content-protected.

Check the disc's write speed to ensure that it is within the speed capability of your burner. Some burner drives write data on CD-RW using 4X speed only. If a higher speed disc (such as 10X or 12X) is used, such burner devices will not be able to properly recognize the disc and may treat it as a CD-ROM or corrupted disc.

The message appears when files to be burnt are open or when you rename/delete files while burning the disc. Do not access or make changes to the files during the burning process.

If burner devices using a USB 2.0 connection do not function well with Ulead Burn.Now in Windows XP, update your system to Windows XP Service Pack 1 and then update the USB driver.

Problems in performance and stability may occur with some IDE burners when they are externally connected to the computer through a USB 2.0 or IEEE-1394 adapter box. If the program is not responding during the burning process, try connecting the burner drive internally (that is, directly to the IDE interface).

Some burner drives, especially DVD burners, are selective with certain CD/DVD media brands. When purchasing blank media discs, check the disc's compatibility with your burner drive.

One way to check the read/write compatibility of a disc with the burner is to select Recorder: Disc Information in Burn.Now. A disc error, disc not readable, or disc type error message may be displayed if the inserted disc is incompatible with your burner. The following message may also indicate that your disc is incompatible with the burner: "The program cannot perform the task you selected using the current disc. Please check your disc and try again." If you encounter any of these messages, try using another media.
