I'm not sure about that... the italian soundtrack is (should be) Dolby Surround encoded, thus have the left, right, central and surround channels encoded into a stereo track; decoding those channels, is it possible to take only the central one and including it in the corrispondig place of, e.g., the english AC3 5.1 soundtrack; the quality will not be the same, as the best Dolby Surround ProLogic decoder has around 40db of separation, but should be sufficient to result into a better surround italian soundtrack than the original; the same could be done for the other languages... mmmhhh, you inspired me a bit...

I don't know, man, if you take the center channel out of the english 5.1 you can still hear the voices in the remaining channels.
