If you really feel like hacking -- take a look at the code of dvgrab instead of
that of kino (unless dvgrab has the same problem, but I doubt it) -- it is much
shorter, and since it doesn't do much else besides grabbing streams from 1394
device and writing an avi file it is much easier to find your way around it.

Until then, if you want me to take a look at the problem, please show me (try
not to annoy the rest of the list with big posts though -- private mail or a
link would be fine) the output of the following:

$ ohphone -t 3 --videoreceive x11 -l -n --videodevice /dev/video1394/0 
$ ohphone -t 3 --videoreceive x11 -l -n --videodevice /dev/raw1394
$ ls -l /dev/*1394

I assume ohphone is behaving the same way as gnomemeeting. The output of
gnomemeeting --debug 3 would be just as welcome, but it is a habbit of mine to
debug pwlib with ohphone and it is small enough for the compilation to take
almost no time at all.
