The driver dev made it default to PAL. This is annoying if you are in North America. norm=NTSC will force it to NTSC however if you observe dmesg you will see it tries PAL then NTSC. cx231xx #0: do_mode_ctrl_overrides : 0xff cx231xx #0: do_mode_ctrl_overrides PAL cx231xx #0: do_mode_ctrl_overrides : 0xb000 cx231xx #0: do_mode_ctrl_overrides NTSCI guess if the dev lives in Europe he is going to assume everyone uses PAL. mplayer tv:// -tv driver=v4l2:device=/dev/video0:norm=NTSC:width=720 mplayer tv:// -tv device=/dev/video0:norm=NTSC Now with picture and sound. Note: If you see a green picture with flickering lines at the top, then mplayer is attempting to play an NTSC video as PAL. Again, the dopey kernel driver assumes PAL unless you specify NTSC. You can see the problem in dmesg: cx231xx #0: do_mode_ctrl_overrides PAL We can test using gnome-mplayer which is the graphical gnome version part of the deb package gnome-mplayer installed via the command: sudo apt-get install gnome-mplayerNow with picture and sound.gnome-mplayer does not accept some of the same command line switches as mplayer. It wont accept norm=NTSC.
