Efficient image drawing

[Paul Davis <pjdavis engineering uiowa edu>]

Howdy,

I'm developing a video playback app and I'm a bit curious to see if 
there's a better way to render images to the screen.  As it is now I'm 
using the Gtkmm objects and copying images from my non-standard format 
in a GdkPixbuf and then drawing to a GtkDrawingArea using 
gdk_draw_rgb_image_dithalign.

Admittedly, this method is fairly fast.  I'm getting between 15 and 20 
fps on my development machine which is only a 1.4 GHz.

I'm just wondering if anyone knew a more efficient method to get image 
data from disk to the screen.  Any suggestions are welcome.
