cut/paste what it outputs.  mainly interested in if you are getting a guid

juser@e18:~/temp$ dvgrab
Found AV/C device with GUID 0x002011010f00256d
""     0.00 MiB 0 frames
Capture Stopped
Error: no DV

if no guid:
plug in firewire, turn on cam, dmesg, look for
[74342.700195] ieee1394: Node paused: ID:BUS[0-01:1023]  GUID[002011010f00256d]


juser@e18:~/temp$ dvgrab -guid 002011010f00256d
Established connection over channel 0
""     0.00 MiB 0 frames
Capture Stopped
Error: no DV

or if the device sends DV:

juser@e18:~/temp$ dvgrab -guid 002011010f00256d
Established connection over channel 0
Capture Started
^C"dvgrab-002.dv":    31.81 MiB 278 frames timecode 00:00:09.07 date

$ man dvgrab
dvgrab will also output raw DV or HDV to stdout    while capturing to
a file if stdout is piped or redirected.

I missed that too, and filed a feature request :)
