New code to make sure intro screencast plays in QuickTime if available or default (usually Safari) if not.

gistfile1.h

- (IBAction)play:(id)sender
{    
    // Open up the intro movie, using in pref order, QuickTime, QuickTime X 
    // or the system defaul (usually Safari).    
    if (![self openIntroMovieUsingAppBundleIdentifier:@"com.apple.quicktimeplayer"]) {
        if (![self openIntroMovieUsingAppBundleIdentifier:@"com.apple.QuickTimePlayerX"]) {
            if (![self openIntroMovieUsingAppBundleIdentifier:nil]) {
                NSLog(@"Could not open intro movie.");
            }
        }
    }
}

- (BOOL)openIntroMovieUsingAppBundleIdentifier:(NSString *)appID
{
    NSString *movieURLPath = @"http://media.clickablebliss.com/profittrain/screencasts/IntroductionToProfitTrain.mov";
    NSURL *movieURL = [NSURL URLWithString:movieURLPath];
    return [[NSWorkspace sharedWorkspace] openURLs:[NSArray arrayWithObjects:movieURL, nil]
                           withAppBundleIdentifier:appID
                                           options:NSWorkspaceLaunchAsync
                    additionalEventParamDescriptor:nil
                                 launchIdentifiers:nil];
}
