Re: QTMovieLayer and renderInContext:

Hi John,

I'm not sure that I understand the question but if all you want to do 
is put a movie layer into a view I have a simple example here that 
works for me;

- (void)awakeFromNib {
    NSString *moviePath = @"your path here";
    NSError *error = nil;
    movie = [QTMovie movieWithFile:moviePath error:&error];
    [movie autoplay];
    QTMovieLayer *layer = [QTMovieLayer layerWithMovie:movie];
    [self setLayer:layer];
    [self setWantsLayer:YES];
}

This awakeFromNib is from my view class that takes up the whole 
window. The movie plays when the app starts.

In the example (that I've not posted yet but will soon) on my blog I 
have a 'play' button that sits in the view that the movie plays on and 
it works like a champ.

HTH,
