OK, I gave the test recording a try via firewire and got the following 
error in my backend log:

2008-06-02 18:00:04.034 Canceled recording (Recorder Failed): Law & 
Order: Speci
al Victims Unit "Limitations": channel 3222 on cardid 6, sourceid 3

I was expecting the channel change script to run, change the channel on 
the STB, and start recording.  Obviously, it failed and that didn't 
happen.  How do you tell your firewire to do this?  I'm unclear as to 
how the firewire recording process happens.

Thanks,
Harry
