It can't open the device. You probably aren't in the right group for access. |

I suspect it'd be the video group, just do: |
| 11 |
|
| 12 |
ls -lhd /dev/video0 |
| 13 |
|
| 14 |
...and see what the permissions are, it's probably going to be root:video. |

For my mythtv card, I know for sure it's root:video. |

If that's all it is, use gpasswd and add yourself to the group then log |
| 19 |
out and in again. |
