B-1. Checking DirectX Version and Video Information
When installing CDR Video Manager for your USBCam, you will be prompted to install
the latest version of Microsoft's DirectX files on your system. We strongly recommend that
you install these files as earlier versions of DirectX (prior to DirectX 8.1) are not
compatible with USBCam. In the event you experience video problems with USBCam,
please verify that your system has properly installed DirectX version 8.1 or later by
performing the steps below.
Video quality and performance is also affected by the amount of video memory available.
By running
diag.exe
, as documented below, and checking the
Display
tab, you can verify
the amount of video memory available on your graphics card.
