Make sure the drive you’re using (a hard disk drive or DVD drive) is using DMA (if your drive
supports DMA transfers). To use DMA:
Note:
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.
Tip:
If your computer has more than one hard disk, you may get better results if you play back
video files from a disk
other than
the one where the Windows swap file is stored. The
Windows swap file is usually stored on drive “
C:
”.
WA R N I NG :
Not all drives support DMA well. For more information, see the documentation
that came with your hard disk.
