20110211 Video Setup Problem Centered Yellow Vertical Stripe

Playback error gives a centered yellow vertical stripe in video window. The yellow shadow image seems to be 180 degrees out-of-phase horizontally, as you can see the left & right edges of the screen split the yellow 'E' character in the shadow-image of 'TED'.

 

What is causing this?

It works fine on the Windows7 box with appearently all the same settings.

But on WindowsXP this yellow stripe shows up.

Could it be the fact that the computers are using different video cards?

Is there a setting I can use to correct the error in CODEC configuration settings on XP?

Even a correct technical diagnosis of this problem would help, as I don't even know what to CALL this kind of error, only how to describe its visible character.
