As far as I am consirned, I stopped buying (and selling) philips a long time ago. Philips went a long time ago from engeering to selling (putting labels on products that you don't manufacter) . (An old school teacher of mine was an ex-development-engineer at Philips, I got the full inside info about it from him).
I got 4 creative webcams pro (based on OV511 chipset) ,which works flawless.
