finally found out that only in Window 7 the .mov file is supported by Window Movie Maker..
let try with my PC with Window 7..it try to install Window Essential but take too long time, i come back to Vista now and found that can use codec to enable this..
after instal this codec, window movie maker can run .mov file now..yes..
now it take too long to publish...not working..cannot publish..
found avs but need to pay, free version got watermark in the middle of the video..
found this converter, pretty fast and simple to use..
