more of the video devices may be degrading the quality of the video signal. Demodulators,
long cables, cable extensions and improper connections can all affect video signal quality.

Solution
If your video equipment supports it, use S-video connections. For more information,
see
“Connection setup”, page 20
.

Solution
Try changing one or more video devices.

If possible, use fewer connections. For example, don’t use cable extensions.
3
Cause
The image settings on your TV may need adjusting.
1
Solution
Some TVs have an aperture control sometimes called
PICTURE
. Lowering this setting may
reduce this problem. Reducing your TV’s brightness setting may also improve image quality.

Problem
Can’t record video with a video recorder
1
Cause
The video source may be copy protected. Your Matrox product may not let you make copies
of copy-protected video. (Some video sources let you make a copy of a video, but you may
not be able to make a copy of that copy.)
1
Solution
To get copies of a copy-protected video, contact the vendor of the video.

Problem
Sound doesn’t record, video files play back with no sound, or sound output is
distorted or too loud

Cause
If the sound problem is with a particular device (for example, TV or speaker), the volume
control on the device itself may need adjusting.
1
Solution
Adjust the volume control on the device itself.
