Basically, it is possible that on a ClearQAM channel, no CCI
information is set (not the same as CCI=0x00), which causes a
CableCARD device to then look for other protection schemes, whereas a
ClearQAM tuner will just tune an unencrypted (but possibly still copy
protection flagged via something besides CCI) and ignore any flags

In my area, this is not the case and my Ceton can pick up anything my
HVR-2250 can as well, but the ClearQAM tuner lets me use MultiRec
which allows nice overlapping recordings by a minute or two to ensure
I get all of the program.  You don't get to use MultiRec with a
CableCARD tuner.
