web video clips unwatchable

I recently ran windows update.
since then when I run video clips from a web page (using Real or Windows media player) the colours are very washed out and the clips are unwatchable.
Any ideas of how I can fix this?

Hi Computron,

Apologies for delay.
I've reinstalled directX drivers and also S3 drivers.
No avail.

The problem shows up when I go to the bbc news website and click on <Latest news in video and audio> button at top left corner. I click Headlines and then on any of the news items. The clip then runs OK unless I click on full screen.
In full screen the clip colours are washed out or inverted or something and is unwatchable.

ok, I have a better picture now of what you mean. Check to see how many colors you have setup in your settings.

To change your color depth in Windows

Choose Settings/Control Panel from your Start button.
Double-click Display.
Click the Settings tab.
Change the Color palette setting to High Color (16-bit) or True Color (24-bit).

Makes no difference.

I've confirmed that the video settings on my PC match those on my laptop which can run the clips in full screen OK.
colour depth, screen res, monitor refresh rate.
The laptop has a different ( & much older) video adaptor but apart from that settings are the same. both have 32mb video memory.
Also this is a recent change in behaviour; it was working before.
I've recently started using a new flat screen monitor but the problem doesn't go away even if I plug in the old CRT .

Have we tried swapping out the VGA cable ? (cable from video card to monitor) Any bent pins ?

Also try going into windows media player and experiment with these settings at
Tools>Options>Performance>Advanced
try changing the overlay or video mixing renderer or lowering the acceleration to see if this problem clears up.

It's working now, tho I can't say why.
I ran windows update again several times and it downloaded an earlier video driver.
I also ran a dvd in full screen and it worked and the bbc newsclips are viewable in full screen mode.
All very odd but at least it's cleared up.

you can have the points as it's working and yuo're the only one who replied and at least gave moral support!
