You know, after reading Eric's response, I'ma bit confused. USC definitlely  
added the GROUP='disk' line to my 50-udev-default.rules file, but it seems  
like Eric is saying that it is supposed to change the group to 'video'.  
Although, maybe it did this when I unchecked raw1394 access in the USC GUI  
at some point. So the other question I have is, if you're saying that USC  
is supposed to be putting firewire devices in the 'video' group, does imply  
that I should just be making a 'video' group and putting myself in it? As  
opposed to the 'audio' thing I have been doing (which is, I believe, what  
was recommended practice for Ibex)?
