[J7N]

I am not familiar with this exact pirate release. However, embedded text subtitles can be turned off by pressing "S" while the movie is playing, or disabled at all by going to Options -> Preferences -> Subtitles and activating "Subtitles disabled" checkbox.

If you are using ffdshow to render subs, then uncheck "Subtitles" in ffdshow's array of filters.

Any form of subtitles is small in size and can remain in the video file without doing much harm.

Instead of the video format, please tell us the format of subtitles (text or graphical) and the software you are using to display them: BSPlayer, VSFilter, ffdshow.
