You can cat /etc/KnoppMyth-version to find out. You are somewhere 
between R5A12 and R5D1 (those are the two versions I am running). 
Regardless, they both use the same structure, I have

/usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw

on both of them, and they appear to be the same files. Mine are:

root at htpc:~# ls -l /usr/lib/hotplug/firmware/v4l-*
-rw-r--r--  1 root root 262144 May 26 05:35 
/usr/lib/hotplug/firmware/v4l-cx2341x-dec.fw
-rw-r--r--  1 root root 262144 Jul  1 17:18 
/usr/lib/hotplug/firmware/v4l-cx2341x-enc.fw
-rw-r--r--  1 root root 155648 May 26 05:52

You may not have to symlink it. Although, KnoppMyth should have put them 
there by default...
