= PRB: Mastering Visual FoxPro CD Gives Choppy Video Performance =

Q139199

-

The information in this article applies to:


 * MSPRESS Mastering Microsoft Visual FoxPro 3.0, version 1.0

-

SYMPTOMS
When playing videos in Mastering Microsoft Visual FoxPro, you may experience choppy videos.

CAUSE
The choppy video playback is usually the result of a slow transfer rate from the CD-ROM drive. This can be caused by one of the following three factors.


 * There may be a terminate-and-stay resident (TSR) program or disk-caching program that is slowing the transfer rate from the drive. Remove unnecessary TSRs from your Autoexec.bat and Config.sys files and from the LOAD= and RUN= lines in your Win.ini file.
 * The CD-ROM drive may not be Multimedia PC (MPC) compliant and may not meet the transfer rate requirement. Upgrading to an MPC-compatible CD-ROM drive will eliminate this problem.
 * A lack of available memory (RAM) can cause choppy playback. Adding additional RAM speeds up the playback.

RESOLUTION
Identify and eliminate the cause of the problem.

STATUS
Microsoft is researching this behavior and will post new information here in the Microsoft Knowledge Base as it becomes available.
