The following troubleshooting items address problems related to video files.

1

Cause

Your hard disk may be too slow.

Try defragmenting your hard disk.

Windows 2000 – To defragment a hard disk, click

Solution

If possible, try using a faster disk.

Solution

Make sure the drive you’re using (a hard disk or DVD drive) is using DMA (if your drive 
supports DMA transfers). To use DMA:

Click

(double-click*)

. (* Depending on your version and 

configuration of Windows, this part of the step may not be necessary.)

Double-click the 

list item to expand it, then double-click the 

name of the appropriate controller.

Change each 

 setting to “

Click

Jerky video file playback may be the result of slow playback or recording. Slow 

recording causes frames to be dropped (frames aren’t recorded). If jerky video is caused by 
frames that were dropped during recording, the problem can only be fixed by recapturing 
the video under better conditions.

 If your computer has more than one hard disk, you may get better results if you play 

back or capture video files with a disk other than the one where the Windows swap file is 
stored. The Windows swap file is usually stored on drive “C:”.

Not all drives support DMA well. For more information, see the 

documentation that came with your hard disk.
