Subject: Re: [PD] pdp and webcams
Thanks Tom,
I'm wondering if anyone can recommend a camera that they are
using with pdp/pidip . I've tried using the Labtec camera
(same driver as Logitech Quickcam express) which works with
Gem (extremely slow) but not pdp.
Tom suggested a camera with the Phillips Chipset. I haven't
seen any Phillips cameras here but it appears that the
Logitech Quickcam 3000 and 4000 use the Phillips chipset. So
anyone using the Logitech Quickcam 3000 or 4000 with pdp??
Has anyone got the Labtech camera to work with pdp.
Thanks,
Jim

if it's the double buffering, it means you're stuck. maybe i will

consider buying a camera with a philips chipset. they are a little
