I don't know anything about Firewire, and can't seem to get through to
the specs, but a look at the code tells me that the only format that
receive routine knows is CIP_FMT_DVCR (which happens to be zero).  

You'll need someone who can figure out what the format you're getting
means, and how to handle it.  The recent comitters to the fwcontrol
utility would be a good place to start.
