webcam works on one of two Lucid systems

[Marlon]

(default language pt-br, sorry en-us errors)

Hello!
for debug i´ve used mplayer to test my webcams
for me, your problem seems to be driver..

apt get some libs (video4linux,v4l-conf, xawtv, xawtv-plugins, v4l or v4l2
)

mplayer tv:// -tv driver=v4l:width=352:height=288:device=/dev/video0

IF (v4l2)

mplayer tv:// -tv driver=v4l2:width=352:height=288:device=/dev/video0
