Re Create a movie from a memory pointer

I have find an article from the apples's quicktime develop
center:http://developer.apple.com/qa/qa2004/qa1341.html
It is a Q&A:
Q: I can create a movie from a movie file using the |NewMovieFromFile|
API, but how do I create a movie from movie data which resides in memory?

I think this is what I need,but when I do it like the answer says,error
occurs;
The error is -2048 ,when I call the NewMovieFromDataRef.

Who can tell me why? Or is that answer right?

Help me please!!

You need to tag the DataRef correctly so QT knows what to do with the data in memory. In the Q&A you mention there is a link to TN1195 which discusses this in detail.
