Problem with wmp11. when i play dvd with subtitles, video bcomes black&white. without subtitles, video is ok.? - klite wmp11

Klit Codec Pack installed. I use XP with Service Pack 3 fixed. When playing DVDs, my wmp11 video is in black and white when subtitles are. If the subtitles are turned off, the video is very good. What could be the problem?
