Microsoft Lifecam Cinema

Hey everyone,

Does anyone have any experience working with the Microsoft HD Lifecam Cinema webcam?

Specifically, I am trying to stream in HD 1280x720. I have tried the VideoIn tutorial (attached) but can only stream in 640x480 no matter what settings I use.

Any help or insights would be appreciated.

Thanks!
