Hi, i have windows xp sp3 but i can't get the effects of windows movie maker to work although they were working good in past. Also when i do right clip on any of them the choice to play the clip isn't available. I have reinstalled movie maker and removed codecs but they still don't play. Has anyone anything else to suggest me to try? Or if u could tell me what other windows files or components the movie maker requires to work well thx!
