Permanent subtitles

Regardless of the movie that I watch, and the content, via xbox 360, the subtitles are always showing. For example, I’ll watch Start Wars VI, and the subtitles will always be present, even when there isn’t a need for it. I’ve also tried to disable the ‘force subtitles’ from the server end. My subtitles come directly from the movie that I ripped via DVDFab. I’ll watch movies in different formats, but the most common format is .mp4. What has me totally stumped is that I can watch the same movie on my laptop, iPhone or iPad and the subtitles won’t be there. However, on the xbox their always present.
