Print to Video help please

Thanks, my first post.
OK, the deck is a Sony DVCAM.
I am using Final Cut Express on a MacBookPro 10.4.11
I have a firewire cable connecting the two. (I also tried using my Panasonic DVX 100B camera with the same result - audio but no video).
I chose Refresh Video Devices
Clicked on the timeline, then Print to video.
I gave it 6 seconds of color bars, then when it said it was 'ready, I hit return and the deck began to record.
I cannot see any video on my monitor, (or int he camera screen), but I do see the audio meters moving. During playback the audio is there but no video.

Thanks for any help/suggestions. Very much appreciated.

I have also done this thanks to a response to another post for print
to video issues:
- Trash your preferences, reboot, and launch the application, set the correct DV setting, and see what happens. I went hee for those instructions: http://www.fcpbook.com/Misc1.html

Still I get audio but no video - still searching for a resolution to this problem.
Thanks for anyone who can help.

Interesting - I was just reading your bio here http://www.fcpbook.com/Who.html when you replied.
I have the Sony DSR-40 DVCam deck.
Am using input select: input DV setting
I do not see the sequence in the external monitor or when I use my camera for output. I see the words Video Marker on the black screen.
Yes, I have fully rendered the sequence.
I will try another firewire cable.
thanks for your reply.

I tried another cable but still no change...hmm
