Right after I sent the last message, I looked at my logs and didn't see 
any of the "Problem with capture cards" message.  I also noticed that 
under the Capture Cards in mythtv-setup, the GUID was being shown now.  
It used to say "[Firewire: ]" (notice the blank after  Firewire.  Now it 
says "[Firewire: 00159AFFFE163F4A]".  For some reason it wasn't being 
picked up before and now it is.  I don't really know why.

I have a test recording set to record a show over the firewire 
connection to check it out.  Its due to start in 5 minutes (from when 
I'm typing this).  I recall putting the channel change script into one 
of the setup screens during my earlier setup steps, so I hope it'll 
change the channel and start the recording for me.  If it doesn't I'll 
let you know.

I appreciate all of your help and ideas.
Harry
