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
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..
