I tried this out, and had a couple of oddities in my results.

First, almost all unencrypted channels (tunable via ClearQAM) were
reported as "Unknown / None". The one exception was reported as
Unknown / Copy Generation Management System - Analog: "One Copy"
(0x02). This channel is viewable over ClearQAM and FireWire, but not
the Ceton.
Second, all channel's to which I don't subscribe were reported as Copy
Control Information: "Copy Free" (00)

The fact that the Ceton falls back to CGMS-A for unencrypted channel's
in my case means that the statement "if you can record it over
FireWire, you can record it with CableCard" is not entirely true....
