cam-canopusbox(via firewire)-vlc-stream

[paprika]

hello,
i have a problem to stream my cam.
i have checkt many things in this forum but nothing works.
is it possible to stream over firewire device? with dvgrab or something like that?

I do it in this way but nothing works:
dvgrab - | vlc --no-sub-autodetect-file - :demux=rawdv ":sout=#transcode{vcodec=WMV2,vb=256,scale=1}:duplicate{dst=display,dst=std{access=rtp,mux=ts,dst=xxx.xxx.xxx.xxx:1234}}"

it looks like the vlc have no device,
the vlc does no picture in this way:dvgrab - | vlc --no-sub-autodetect-file - :demux=rawdv "
is this normal?
i go crazy,whats the problem
thank you
