You know whats with the UK Bd of Conan?
It seems to contain a different Video Version. So it might contain another audio mix, too.
In the Scene at about 104:36, when in the US Version the Women on the Stone is telling Conan that Thulsa will come, the UK shows instead a longer scene with Conan and Subotai preparing the Battlefield and talking about winds and storms before battles...
Here is a German comparison between UK and US BD regarding the different scene with pictures:
