Was able to quickly chat with Ben Burtt and Matthew Wood about the foreign language versions at Celebration VI. Burtt recalled around 20 versions made over the years. The general process was Lucasfilm would provide the Music and FX track to the overseas companies who would hire the actors for the dialog dubbing and record the translation. Those recordings would be sent back to Lucasfilm who would complete the final mix with the assistance of someone who spoke the language so the mix wouldn't step too far on the dubs.

Woods remembered completing around 8 mixes for the 2011 blu-rays. He referred to F.I.G.S. (French, Italian, German, Spanish) http://en.wikipedia.org/wiki/FIGS but time was short and wasn't able to confirm the others. Am going thru the international Fox sites to get 2011 information.
