The problem with the Turkish dub is that the dub was made for the 1997 version, so when released with later edits, the dub of the ESB Vader/Emperor scene is reverted back to the English version (because the dubbed Turkish dialogue no longer matched the altered scene). If there was a complete Turkish dub, it’d have to be from VHS/Laserdisc/TV broadcast of the 1997 version. I’ll PM you for more info.
