Ok, here goes.
If you own the NTSC version of the game remove the movies that has the word "extra" in them. I hope you are familiar with Xbox ISO creation/extracting/backuping.
For PAL version this is what to do:
remove the movies with "extra" in them
remove sound files for the language you do not use.
FR
GE
IT
SP
So if you don't use french simply remove the ones with "FR".
Now you should have a working DVD5...
