Sorry but current version of iPi Recorder is not compatible with Microsoft Lifecam HD 5000. The problem is, iPi Recorder only supports standard 4:3 resolutions and Microsoft Lifecam HD 5000 is a widescreen 720p camera.
You can try the following workaround:
Delete Microsoft drivers for Lifecam HD 5000 and reboot the system. Connect the cameras. Windows should offer you to use generic UVC (
http://en.wikipedia.org/wiki/USB_video_device_class ) drivers for your cameras. In UVC mode, your cameras should support 4:3 resolutions.
Please note that recommended camera for use with iPi Desktop Mocap is Sony PlayStation Eye.
