Yes, no HW acceleration is used.
Your graphics card may still support overlays but not the kind we are 
looking for. VLC outputs frames in YV12 color format (see 
http://www.webartz.com/fourcc/) so we require the graphics card to be able 
to display YV12 overlays which it doesn't seem to be able to do.

However, we are currently working on a scheme which would allow us to find 
the closest possible mode supported by your graphics card and use this with 
a color format conversion plugin. This will allow graphics cards that don't 
support YV12 overlays to still be able to benefit from some kind of HW 
acceleration.
This work should be ready for the next major release of VLC (0.5.0).
