Description-en: utilities for use with the ivtv kernel driver
 The IVTV project develops a kernel driver for Linux and a driver for
 X11 for hardware based on Conexant's CX23415/CX23416 codec chip such
 as the Hauppauge PVR 150/250/350/500 models and other supported hardware.

there is also firmware-ivtv and xserver-xorg-video-ivtv. I htink you have
those, but who knows. I would try this way anyway

Try using following to grab the camera

mplayer -fps 10 -tv driver=v4l2:width=640:height=480:device=/dev/video0

-fps in my case 10 is compromise - you can try higher values

note v4l2 ;-)
