You realize you're adding on quite a bit of baggage for each language track you add, right? I forget exactly how long your edit is, but I think it's around 90 minutes. A stereo dolby track (AC-3) running 90 minutes with a bitrate of 192 kbps is about 126 megabytes in size. With the four language tracks you have, you have 500 MB worth of audio as it is.

Why not cut the less common audio tracks (HUN & CZE), and instead use foreign language subtitle tracks? You could add in 20 different languages if you wanted, and it would take very little room, compared to using all those audio tracks.
