As far as I can tell the camera is working fine.

For example I can send DV data *to* the camera over firewire and it
happily converts it to analog and ships it out s-video to the TV.

And the data *from* the camera is recognized as DV:

	fwcontrol_prev -u 1 -R camera.dv
	Detected DV format on input.
	(EAGAIN)
	(EAGAIN)
	(EAGAIN)

The camera was of course powered off while I tested the argument
range checks.  And I only ran tests that seemed safe.  I'm not
*completely* insane.
