Note that with the firewire ports rendered impotent by the last software upgrade, it really doesn't matter what state the 5C flags are in. And TWC (my provider) likely knows this, as my diagnostic page shows that they don't even have the flags turned on anymore. The same is true of the SA3250HD, which was the STB they gave you if you wanted active firewire (per FCC mandate, which they no longer concern themselves with). If you're going to prevent any HD dumping to tape by neutering the firewire ports, why bother with 5C?
