Divxplanet.org or altyazi.org is shut down and the admins have officially announced it.
service.subtitles.divxplanet
will never work again, i suggest to remove this one from repo, may be in future i can write a service addon for.
turkcealtyazi.org
planetdp.org (this is supposed to be the continuation of divxplanet but it has a very weak content of subs.)
or all combination of them but right now opensubtitles are good enough for turkish subtitles.
