I just verified that they match.  I tried using the 6200ch program 
earlier to change channels via firewire and it failed, so I removed the 
cable and put it back in, and it worked again.  However, I still have 
the same problem trying to record (same errors I should say).

Has something changed in the mythtv-setup on the 0.24 upgrade that would 
cause the backend to fail in changing channels?  It seems like this is 
where the issue is.

I can put up more logs or info if anyone wants to see it.

Thanks,
Harry
