HP C4381-90100 manual Video is choppy, Buffer underrun error messages

3-4 Common Symptoms and Solutions

■Try listening to the wave files on your hard drive to see if they sounded poor before copying them to CD. (You can use the Media Player program found under Multimedia in Windows’ Accessories.)

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).

■Upgrade your video card.

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

Buffer underrun error messages

When using Easy-CD Audio or Disc Copier:

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

■Buffer underrun may be caused by hard drive compression software (page 3-6).

■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 programs improve access times to the hard drive, which will help improve system performance while writing to and reading from the CD-Writer Plus drive.

Buffer underruns could also be caused by an unsupported parallel port (standard mode SPP). See “Minimum System Requirements” on page A-
