Many thanks Anton and Jack!  Changing the permissions and group (video) 
on /dev/raw1394 got me a little further but there is still a problem. 
Coriander now comes up and shows "VIDERE_DESIGN MDS-STH" under the 
Camera Select menu but the window is completely unresponsive--clicking 
on tabs and buttons has no effect.  Typing Ctrl-C in the launching 
terminal kills the coriander window but does not return the command 
prompt and coriander is listed as a defunct process.  Also, trying to 
run smallv simply hangs after issuing the command--no window ever 
appears and neither Ctrl-C nor 'pkill -9 smallv' in another terminal can 
kill it...

Just to summarize:

ls -l /dev/raw1394
crwxrwxrwx 1 root video 171, 0 2011-02-12 08:57 /dev/raw1394

uid=1000(patrick) gid=1000(patrick) 
groups=4(adm),6(disk),20(dialout),24(cdrom),44(video),46(plugdev),104(lpadmin),115(admin),120(sambashare),1000(patrick)

ls -l /dev/video1394/
total 0
crwxrwxrwx+ 1 root video 171, 16 2011-02-12 08:57 0
crwxrwxrwx+ 1 root video 171, 17 2011-02-12 08:57 1

Any other thoughts?
