Subtitles require transcoding, and the xbox can't handle 5.1 in the transcoded video. You can try the Magma release that a user created to change how PMS transcodes to a format better supported by the xbox. Just search the forum for magma.
I provide NO application support via PM or email, so please post your question to the forum.
