Yes. It returns nothing. All I get is another command prompt.

Yes, I did that. It says to make sure that libraw1394, libavc1394, and 
libiec61883 are installed. I checked Add/Remove Software and yes, they 
are all installed.

After plugreport, the Wiki is to run plugctl:

[mythtv at localhost ~]$ plugctl -n 1 "oPCR[0].n_p2p_connections=1"
raw1394 - couldn't get handle: Invalid argument
This error usually means that the raw1394 driver is not loaded or that 
/dev/raw1394 does not exist.

Sure enough, I don't see /dev/raw1394. But I don't know how to load the 
raw1394 driver.

Another person suggested that I check if the firewire module was loaded 
by running lsmod and this is what I get:

[mythtv at localhost ~]$ lsmod | grep firewire
firewire_ohci          17244  0
firewire_core          36453  1 firewire_ohci
crc_itu_t               1223  1 firewire_core
