I have experienced the follwoing:
* install dvgrab
* succesfully grab videos from a Canon HV30
* some days later, I got:
[EMAIL PROTECTED]:~$ sudo dvgrab -i
[sudo] password for m:
raw1394 - failed to get handle: No such file or directory.
[EMAIL PROTECTED]:~$ sudo mknod -m 666 /dev/raw1394 c 171 0
[EMAIL PROTECTED]:~$ sudo dvgrab -i
Error: no camera exists
Somewhere I read about a user who just changed the PCI-plug for the
card. This didn't help here either.
lscpi gives:
