fwcontrol -R can't work

[tzhuan]

Hi:
Sorry for my poor English. :-)

I have a laptop running FreeBSD 6-current. It's IBM X30. I want to use
it to record DV, but I get following error:

huan# fwcontrol -R tmp.dv
NTSC
01(249 blocks padded)fwcontrol: unknown format 0x5
huan# 

The DV is Panasonic NV-GS5.

I don't put the firewire in kernel, I load firewire.ko at boot time
instead. Following is the dmesg:

...

Any suggestion? Thanks very much! :-)
