I tried to help but struck out. There are two device codes listed at
http://www.hifi-remote.com for Samsung cable boxes.
0144, 0040
There are no advanced codes listed for these device codes at
[Link: hifi-remote.com] There are no .CCF files for Samsung cable boxes in the Pronto files section at RemoteCentral.com
The next step is to analyze the signal from your OEM remote using a Pronto or a JP1 interface. I don't know if you have access to either.
