Well, they'rea fansubs, so the subtitles are like merged with the video file, you can't extract them or anything. By cut off, I meant that on a TV screen, not the whole picture is shown (some of the bottom, top and sides gets cut off a bit) and the subtitles are part cut off. If I recall correctly, there's something called a "TV Safe Zone", and the subtitles get cut off a bit there. Anyways, I'm not sure how to fix this.
PC-GUY, thanks, I'll check that program out.
P.S: I'll take a picture to clear things up about the subtitles being cut off.
Edit: Here we go, it would be like this
The blacked out parts are the parts that would get cut off, I hope this clears things up!
