Hi
Finally, I succeeded in writing a freeframe plugin for capturing the 
sony PS3Eye webcam with pix_freeframe object.
This permits to use this cam in Pure Data (GEM, Windows only) with great 
performances (see below), with no need to use DirectShow.
You can download bin and sources here.

Test and Enjoy !
