Remove Subtitles from 100 MP4 files?

[Catsrules]

I got the complete series of Stargate Atlantis, and ripped and converted them all to MP4 (I hate switching out DVDs :) ) anyways, some how during this process the chapter's names got created in to subtitles and put in to the MP4 file, so I have "Chapter 1" stuck on the screen all of the time then "Chapter 2" stuck on and so on. This is kinda annoying, and I would like to remove them. I know there are program that will work, I removed a few with mp4UI but being a TV show there is 100 episodes, and I would prefer not having to do them all individually. Is there a way to make like a batch file or something can be copied in the folder and it would remove any subtitles to any MP4 in that folder.

Thanks

A new build of MPC-HC won't display the chapter at the bottom -

Sorry I didn't give much information to what i was playing them with.
I am mainly using windows media Center with the Shark007 codec pack.
I have figured out a way to disable subtitles completely, but that not only affects my Stargates is also affects all of the other shows I have in my media library. Some of them require the subtitles for parts of movies that aren't spoken in my language. I figure that best way is to just remove them.
