Sorry, my description of the process probably wasn't complete..

When I saw this problem I changed the permissions of the raw1394  
device, and then ran mythtv-setup again. Check your firewire input and  
make sure the configuration screen shows the actual id of the device.

If it can't see the device there will be a pulldown menu that doesn't  
contain any data - if it can, there'll be a number in there: the ID of  
the device.

After you have an ID number in the firewire input setup, then restart  
all backends on your system.

Also, check the /var/log/mythtv/ directory for the backend logs.

Hope this helps..
