"Can I use a Digital Video Camera as a video source?
Yes. Any DV camera with HDMI, composite or S-Video outputs that supports a resolution of VGA 640x480 and 30 frames per second or higher will work with Skype. The camera needs to be connected to a video capture card. Skype has successfully tested the following capture cards (others might work but were not tested) for HD film and broadcasting:
ATI graphics cards with video IN, for example, ATI Radeon X1900 GT
Hauppauge WinTV-PVR-USB2
Belkin Hi-Speed USB 2.0 DVD Creator
Pinnacle Analog Pro USB
Skype might need a special driver to recognize the new video source. You can use Graphedit or ffdshow...
