OK, here's what I can't figure out:  When I tune to a channel on source 
1 or 2 (1 being the digital input of the pcHD5500 card and 2 being the 
analog portion of that card), I get the channels.  If I tune a channel 
that is associated with Firewire (which is source 3 in my channel info 
section of Mythweb), the STB changes to that channel, and I get the "You 
should have gotten a lock" message.

The thing that I'm a little suspicious of is when I go to my Backend 
Status page of Mythweb, it shows Encoder 1, Encoder 2, Encoder 3, and 
Encoder 6.  I know what 1, 2 and 3 are, but what's 6?  Furthermore, when 
I had the initial problems with my Firewire, I saw errors in the backend 
logs about "Card6 failed init".  Is it possible that there's a mismatch 
here?  Should I delete all firewire sources/cards and re-enter them?

Here's my backend status:
Encoder 1 is local on HJDMyth and is not recording.
Encoder 2 is local on HJDMyth and is not recording.
Encoder 3 is local on HJDMyth and is not recording.
Encoder 6 is local on HJDMyth and is not recording.

Here's an example of what a Firewre channel is set to in my Channel Info
