Subtittle problem

Hi i have a problem i would like 2 sovle it has to do with subs.

When i rip a movie or do anydvd+clonedvd on some movies not many i get the subs showing all the time eaven if i turn them off they still show.

i know its not my player because i tried different ones eaven in power dvd they show in off mode.

Now my question is. is there a way to have the subs turn off in a tool like lets say ifoedit. or any other way.

Ps i really need the subs to be on since my GF watches subs but i dont.

I really apreciate any help.
