Hello Everybody....

Easy.... I probe it with xawtv and tvtime and work fun

    Now The problem is that when I ran
    >> vlc
    >> v4l:/dev/video0:norm=ntsc:frequency=181000:adev=/dev/dsp:audio=0
    >> --sout-display

    I obtein video but not sound.... then i read in the vlc forum about
    saa7134-alsa and i did

    >> modprobe saa7134-alsa index=1
    >> dmesg
    saa7134 ALSA driver for DMA sound loaded
    saa7130[0]/alsa: saa7130[0] at 0xc0101000 irq 217 registered as card 1
