Perhaps the file was VFR? In that case you need to extract the timecodes as well, open them and the subs in Aegisub (the ONLY sub program that can handle the VFR + hardsubs scenario) and then export them in VFR mode to make them sync. Of course, as long as you're softsubbing they'll still sync... the problems begin when you try to hardsub with VFR.
