Hello.

This what i see in zoneminder:
I can't run the zoneminder with the command:
/etc/init.d/zoneminder start

There is why you have no picture. Shouldn't be /dev/video but /dev/video0.

Its OK. Look at this:
ls -l /dev/video
lrwxrwxrwx 1 root root 6 2006-05-11 19:26 /dev/video -> video0

But it's still owned as root so the processes can access the device. It may be having an issue with the link.

Have you read the FAQ about increasing shared memory?

I read about it but now the old prbolem return after I reboot my computer.
I resolved the old problem by killing some processes, but now i forgot what exactly processes I killed & all my guesses was wrong.
Here is my /var/log/everything/current:
