many cable companies encrypt the signal so that only a cable box can unencrypt 
it, then 5C comes into play as to whether the box will send the signal out 
over firewire.
5C=0 is basically off, ie no 5C device needed
5C=1 is copy once
5C=2 is copy never (ie only for playback to a TV).

I happen to be visiting the folks this weekend and made the discovery that 
their DCT6412 has 5C=0 for EVERYTHING. I'm jealous, and trying to figure out 
how to get this dual tuner DVR to send the video to my laptop, its a lot more 
finicky than my DCT6200 at home.
