i have a foreign film which i need to watch with subtitles, and its a 1 cd divx rip. i have two sets of subtitles, one .smi one .sub for the movie, both part of a 1 cd divx rip but using the caption wmp option doesnt work and when i tried to play them using some crappy subtitle viewer program the subs were off by like 30 seconds

my questions are how can i play the subtitles correctly and also how can i edit the subtitles to put them in the right time in the movie? thanks
