fileOpenMovie --
uses MCI_OPEN to open the AVI file. Saves the device ID so we
can do stuff like find the frame size.
uses MCI_WINDOW to show the playback window
uses MCI_DGV_STATUS_HWND to get a handle to the window
gets the movie length with GetMovieLength, and
positions the movie with positionMovie.
Uses InvalidateRect to get window repainted (which will show
the first frame)
Gives user an annoying messagebox if this doesn't work.
