Why is my video discolored or has colored lines running through it?
A variety of issues can cause color to go bad in Windows Media Player. To troubleshoot possible causes, do the following:
•
Check for video-card driver updates from the maker of your video card.
•
Check for Microsoft DirectX updates by scanning for updates on the Windows Update Web site.
•
Try a different acceleration setting for your video hardware:
1.
In Windows Media Player, click the Tools menu, and then click Options.
2.
On the Performance tab, in the Video acceleration area, drag the slider to None to use basic video-acceleration settings that work with most video hardware. For some video hardware, you must do the opposite (drag the slider to Full) to correct the problem.
•
Adjust video settings to default values:
1.
Click Now Playing.
2.
On the View menu, point to Enhancements, and then click Video Settings.
3.
In the Enhancements pane, above the slider controls, click Reset.
If the video plays back normally at first, but then becomes discolored (or disappears entirely), see the question, "Why can't I see the video when I'm playing a video file?" in the Media Advice archive.
