[H???s?i??]

i dont know if this is the correct forum for this but i wonder if there is some way to eliminate the subtitles of a video that i wanna use to make an amv?

Yes. There's a whole guide written on the various methods of doing just that.

But you really should be buying the DVDs so you don't have to worry about subtitles at all.
