On the subject of the thread, the most troubling difference I see between the Catholic/Orthodox and Protestant Bibles is with reference to the specially announced Name of God in the Song of Moses, i.e. the Rock. The Masoretic text retains the Name, the Septuagint washes over it and the Vulgate omits it.
Interesting - I'd never heard this before. I'll have to check out that research thread you linked to. Thanks for posting it!
