Here's an update on what I'm seeing: I successfully recorded a show on 
one channel the other night, so last night I setup another Firewire 
recording on another channel.  That one failed with the same errors 
above.  So, why would 1 channel work and the other one not?  Could it be 
the 5C encryption?  I was under the impression that once the signal came 
into the box, the signal/stream is unencrypted and the output is sent 
out to the box outputs (HDMI, Component Video, Firewire, etc.).

Any thoughts/ideas/things to try?
