I want to run xawtv. I get the video in black and white and no sound.
I want color and sound.

I get these warnings when running v4l-conf & xawtv:

v4l-conf -a 0xD0000000
v4l-conf: using X11 display :0.0

I added 'Load "v4l" and Load "dga" ' in xorg.conf
Can someone explain the meaning of the warnings and how to correct them ?
