Well although you don't tell us which encryption system this is, I presume it is Irdeto. Certainly the CRD string requesting the coco is the correct string for Irdeto ACS v1.2 cards.
In Irdeto, the counry-code is 3 bytes in ascii.
EG "4e 4c 44" for "NLD" (netherlands) or "49 54 41" for "ITA" (Italy)
But I don't see any such string in the response. Are you sure you've pasted the correct data??

the response will only contain one set of 3 contiguous bytes all of which lie between x'41' (=A) and x'5A' (=Z). So if you have the original string you can easily identify the bytes.
