I'm now capturing digital video. It looks like it was "modprobe raw1394" 
that did the trick (thanks Anton and Kareem). When I had done lsmod, it 
had looked to me that all the modules were already loaded, but weren't.

I still haven't seen any of the video, so am not totally sure dvgrab is 
working properly. When I try to play the .avi file with mplayer, I get 
the error:
"AVI: Missing video stream!? Contact the author, it may be a bug :( " 
 -  in the dv1 format and I get the error:
"Error opening/initializing the selected video_out (-vo) device"   -  in 
the dv2 format.

Now I am trying all the various formats. This is a brand new 
installation of RH9 and I just installed mplayer with apt-get, so I 
can't be sure mplayer is working properly - have to find a movie file I 
know isn't corrupted to test mplayer.

John.
