Certainly. You put the video on once and then add all the alternate audio tracks. Then your “Language” DVD menu will simply pick which of the alternate audio tracks to play. This is one of the basic functions of DVDA.
So, render your video once. Render your audio 8 times. Place the video on the menu and add the “default” audio track as the audio for that video. Now add the additional audio tracks and place the extra languages in those tracks. The menu options you make will simply tell it which one of those audio tracks to use.
