That's the correct location, unless you are using VideoService instead.

The new Fedora AGTk 2.3 beta 1 RPMs contain versions of vic which
incorporate the patch.

You could try running vic directly from the command-line, e.g:
  cd ~/.AccessGrid/local_services/VideoProducerService

Click the menu button, then click transmit and then see if there are any
useful diagnostic messages being printed out.

You might also want to have a look at /var/log/messages and see if there are
any hints there as to what could be going wrong.

Perhaps your webcam doesn't support either YUV422P or YUV420P pixel formats
for capture that vic requires.
