i am somewhat familiar with the app - so i can help with stuff i know about. it is usually best to discuss an app in it's forum, for sure.
as for your raw1394 prob - it's a matter of permissions.
what you need to do is open the file home/dev/raw1394 as root and change it's permissions, so you (user) can read, write and execute. now, that file appears automagically, only when you plug-in your dv camera over firewire. i was surfing the net trying to find a way to have raw1394 file keep permissions, but unsuccesfully so far.
hope this helps
