Hello, I've just returned my Quickcam Pro 9000 and took a Vision Pro (BCD 0.9) and I got exactly the same problem (even worse it seems).
I tried your test, and I only got 23 fps with still a lot of flickering... Same problem with 2 (slightly) different camera and 2 linux kernel (2.6.26 and 2.6.30) ! I really don't know what is wrong here... Thanks anyway for your help !
