</div>That's not true. CCI flags can be set on clear-QAM channels. I don't<br>
know enough about the Ceton to know if it honors those flags in that<br>
case, though.<br>

</div>I've seen some reports of successful firewire recordings even with CCI<br>
0x2 (Copy Once). It seems to depend on the STB you use. Most of them<br>
block this, but apparently not all.<br>

<br>
So even this statement may not be strictly true.<br>

</div></div></blockquote></div><br>What a mess.<br><br>That entire excerpt was from the Ceton support site. If they handle the flags as I posted from their site, then they ignore CCI if unencrypted and only look at the other four flags. If encrypted, they only look at the CCI flag. The Firewire recording example with CCI 0x02 will not work on the Ceton if encrypted, but would work if unencrypted.<br>
<br>Is it possible for some of these flags to not be "present"? Are these optional flags in the packet headers or do they have bits allocated for each one? If there are bits allocated, then what would those bits be set to indicate not "present" as apposed to copy-freely?<br>
