Subtitles do not cycle continuously

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.
