Help! My Movie Music Is Screwed Up!!!!, disaster....fear and loathing... Options

[tokyoroland]

I finished editing my music into my brother's movie in imovie ( the latest one ) on OSX. I burned it to dvd-r and when I play it, the sound totally screws up halfway through the movie!!! This is odd because it works just fine imovie and the qucktime movie is fine, too.

I thought it was a faulty dvd-r, but I tried another one and it did the exact same thing! help! possible errors:

1) the sound was mastered wrong. ( the girl who transferred it to cd from minidisc mastered it at a low level, so I turned up the volume ( normalized it) in Spark.

2) Maybe I didn't format the dvd-r. Do I need to?

It isn't my computer because it messes up on my external dvd player as well as when I put it in my computer and play it.

PLEASE HELP! I don't know what to do, and I really want to finish this film. Should I go back to the music and NOT normalize it??

ANY suggestions will help...
