If I load an AVI file, start playing the file and then pause I can see a
still frame.  However if I cover up the window with another application and
then go back the still frame has disappeared.  No method of refresh seems to
work, and I can't save what is being displayed either because the canvas
doesn't have any display data.  I'd like to know both things: how to refresh
and how to capture the still image.

Any ideas?

Thanks

Maybe you can try to save canvas to TBitmap ... and OnRepaint draw that
bitmap on canvas
