3-4 Common Symptoms and Solutions

Video is choppy

This can be caused by the same situations that cause buffer underruns. This can also happen if your video card is slow. Try the following:

■Try the solutions for buffer underruns (page 3-4).

■Reduce the size of the video window and close any other programs that are running.

■If the previous suggestions don’t work you may want to consider upgrading your video card.

Buffer underrun error messages

CD recordable devices require an uninterrupted data stream from the hard drive in order to write successfully to a CD. A buffer underrun message appears when for some reason the data stream is interrupted. This can occur, for example, if another application interrupts the writing process, or if the CD-Writer Plus drive’s write speed is set too high for the speed at which the hard drive can accesses and transfer data.

When using Easy-CD Creator or CD Copier:

■Make sure you use the Test option in the software to ensure that the write speed is appropriate for your computer. For more information see the application’s online help.

■Make sure your system meets the minimum system requirements (page A-1).

■Buffer underrun may be caused by hard drive compression software (page 3-7).

■NEVER write to the recordable CD while other applications are running that could interrupt the writing-to-CD process. Log off any networks, disable any fax modem, email, screen saver, or other programs (such as TSRs, terminate-and-stay-resident programs) that may automatically send messages to your computer while writing data to the CD. If the interruption is long enough, you could ruin a write-once CD to which you are writing.

■Exit any other programs while writing data to the CD.

■If your computer has a power-management feature, disable it (see the manual that came with your computer).

■Run SCANDISK.EXE and DEFRAG.EXE periodically on your hard drive (see your Windows manual for more information). These
