Well, that's not good.  They should be very different.

The "avcore" firmware is for the analog TV audio broadcast standard
auto-detection.  It is used by the "Merlin" audio core in the integrated
CX25843 core inside the CX2388[578] chip.

The "enc" firmware is for a CX2341[67] MPEG-2 encoder chip connected to
the CX2388[578] chip.

I believe you are correct.
