Video preview doesn't work


after reinstalling my system (XP) - Video-preview doesn't work.
It's no problem to watch videos with WMP 11.

When I open the preview in Opus, it flashes the bar I know from the past when everything worked fine...

... but after that the WMP-bar turns up

I have sound but no picture.

Hm, I don't understand why suddenly the WMP is displayed in the preview.

If the Movie plugin can't handle the file (because the required codecs are not available to it) then the ActiveX plugin may try to show it using WMP.

Ah, understood
