//  Contains:   Some utilities for working with QuickTime movies.

//              All utilities start with the prefix "QTUtils_".

//

//  Written by: Tim Monroe

//              Based on the DTSQTUtilities package by Apple DTS.

//              This is essentially a subset of that package, revised for cross-platform use.
