I have a radeon 8500dv video card that has a 1394 port.
I'm connected to the dv port of a sony DCR-TRV280.
When I use dvgrab, I can control the camcorder. That is, the
interactive commands work. I can Play, Pause, Rewind, etc.
But I can't capture: dvgrab sees no frames. And I get this error is syslog:
Jul 26 13:19:52 localhost kernel: ohci1394: fw-host0: Unrecoverable error!

trl[4000880e] cmdptr[104cdaaf] match[f000003f]
I orginally posted this the the dvgrab list, but thinking about it,
it seems a more generic 1394 problem.
