Playback Of QuickTime Movies With A 3DBlaster Card

Playback Of QuickTime Movies With A 3DBlaster Card

Problem:

When playing back Quicktime's *.MOV files under Windows 3.1x with 3D Blaster-VLB installed (configured with 3D Blaster Display drivers), users may not be able to view the video clips although audio is heard. However, when Windows is configured to native VGA mode (using standard VGA display, i.e., 640x480 with 16 colors), the problem does not persist.

Possible Cause:

Optimized video hardware/driver combination allows QTW to write directly to the video memory speeding up performance significantly.

There could have been some incompatibility between Quicktime and the 3DBlaster's display driver, which optimizes the video using the SVGA hardware by default.

Solution:

Insert the statement "Optimize=driver" under the [Video] section of the QTW.INI file. Example:

[Video]
...
Optimize=driver

NOTE: The "Optimize=driver" is case-sensitive. If the 1st character 'O' is in lower case, it will not work.
