How do you know if jit.qt.mov successfully found and loaded a movie?

Meaning, like a text object, I want a bang or something when it’s done loading, and no bang/message if it did not load. The context is, if the user loads a preset and has moved their files, the exact path name will not work, thus I wish to just send the name of the file and the object will look in the application folder.

The second context is that if the video did load, when it’s in there, you can then auto do things like load the first frame into a pwindow for preview. as is my delayed messages (from loading) sometimes happen late enough, sometimes not.

If the qt object can’t find the file at the specified path, it tells the max window. If it would send that message somewhere else I could bang on "can’t" or the like

any ideas… I’m sure this has been done before, or maybe it’s built in and I’m missing it.

Thanks
