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...

Spark shows a big red "resampling" sign if you play back an 48 khz file on a 44.1 khz system. Logic automatically resamples on the fly since 5.2 too I believe. (something that was very annoying for me in a past movie project as well).

Basically, samplerate conversion should be done by your DVD authoring tool. Nothing you really need to worry about unless you're working with old Avids or something like that.

I think one part of your problem is the whole "normalizing" thing without having headroom. Really sucks, but if you've got some continuous clipping in that file then it might screw up the sound. So.. normalize to -12 db and -then- try it. Digital audio is unforgiving, but 12 db headroom allows for a bit of freedom, although I'd prefer 20db. dunno how noisy your source is.
