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
