How do I tell?  I can't find anything in the FAQ about this.  I assumed
that I need DC, as no devices were found by gnomemeeting with the AVC
plugin.

I used the sources on the gnomemeeting website:
http://www.gnomemeeting.org/index.php?rub=5&path=sources/sources
gnomemeeting-1.2.1.tar.gz
openh323-1.15.3.tar.gz
pwlib-1.8.4.tar.gz

Yes!  I thought of that too!  :-)
The only extra information in config.log is something like
"exiting with code 77".   Does that help?  It didn't mean much to me.

Anyway, I finally figured out how to get the SRPMS to compile under FC4.
 I'll post that information in another message, since it might be useful
to someone, somewhere.

Haven't tried kino, but as I said initially, it works perfectly with
dvgrab without adjusting any settings at all.

Because gnomemeeting did not show any devices when set to the AVC
plugin, I assumed my camera (it's a regular MiniDV camcorder) was not
supported by that plugin. Is there something else I can try?


BTW, when I finally did get everything compiled, I executed
gnomemeeting, and set the plugin to DC.  Gnomemeeting then recognized
device /dev/raw1394.  Hooray!  But then a window pops up saying "Error
while opening video device /dev/raw1394 ... There was an error while
opening the device. Please check your permissions and make sure that the
appropriate driver is loaded."   I checked the permissions for
/dev/raw1394 (and /dev/raw/raw1394, which is the new location for this
device), and even tried chown'ing them to my own userid.  No change.

Any other ideas?   Thanks,
