Mmh, the LIVE apparently can get confused when their are different naming schemes used. Try renaming to something like this (using French as your native language):
My.favourite.tv.show.avi
My.favourite.tv.show.en.srt
My.favourite.tv.show.fr.srt
My.favourite.tv.show.fr.hi.srt
Replace fr with the ISO country code of your native tongue.
