i think HD-T don't allow remuxes with multi audio(Dub) .
Most Central and Eastern European Bluray discs (CEE region discs) comes with Spanish audio HD-T has many CEE releases, so you can look for CEE discs in HD-T and often TWN discs (taiwanese discs) are found with Spanish audio, chinese HD trackers will be a good place to look for those region BDs. and HDClub will be a holy grail for all CEE Discs, Tracker HD-Spain probably from name itself may be there will be a dedicated spanish audio encoders, discs will be available, may be a member there can confirm, this is the review http://torrentinvites.org/f36/hd-spa...-review-83522/
