Cannot Play .avi Files with Number 9 Video Card

 * }

Q137051

-

The information in this article applies to:


 * Microsoft Windows 95

-

SYMPTOMS
When you upgrade from Windows 3.x to Windows 95 on a computer with a Number 9 video card, you may receive any of the following error messages when you try to play .avi files or run a program that plays .avi files:


 * Invalid dynamic link call to a .dll
 * Page fault in mmsystem.dll
 * This program has called an invalid dll
 * Your program is making an invalid dynamic link call to a .dll file

CAUSE
Some Number 9 video card drivers for Windows 3.x add support for DCI functions that can conflict with the DCI support in Windows 95. When you upgrade to Windows 95, the previous Number 9 DCI support is not removed.

RESOLUTION
To correct this problem, follow these steps:

 Use any text editor (such as Notepad) to open the System.ini file in the Windows folder.  In the [Drivers] section of the System.ini file, change the line that reads "DCI=RFMDCI" to read: ";DCI=RFMDCI"  In the [Display] section of the file, change the line that reads "DCI-Support=On" to read: ";DCI-Support=On" Save and then close the System.ini file. Shut down Windows 95 and restart your computer.

NOTE: Most Number 9 video cards also change the "DCI=" line in the [Display] section of the System.ini file. Changing this to read:

"DCI=Display" This solves invalid dynalink problems when you run .avi files.

MORE INFORMATION
Number 9 has developed updated video drivers for Windows 95 that include support for specific features of their cards. These drivers do not correct the problem described in this article.
