A bigger record would be great in order to have a deeper look. Whether crypt8 will work... I have some doubts. If you have a look at the files uploaded from serkanguzel you can see the following (just a few things I noticed):
-You get crypt8 using Colibris CSA-tool; anyway, if you check the 188bytes packets with the crypt8 you will see that except the crypt8 the remaining bytes are not identical. So in my opinion this is not CSA.
-The crypt8 you can get are part of blocks which do have kind of a "structure" at the beginning. The first 2 bytes are somehow repeating in some packets.
-The packets with adaptation field are not scrambled (the bits are not set).
