Needed or not it works and sounds the same. Who is going to play the file by it self anyways? Besides if one wanted to for some odd reason play the file by it self, there's free software out there for the taking.

As far as the file being in sync, there was 2 people and i already checked those spots that Turisu mentioned , and i don't see a problem. Stamper never said where parts were out of sync so i can't check those.

Sorry i ever volunteered to work on this file, i was just trying to be nice and help out.
