Then, for each of the protocols (except lirc, which isn't a real protocol) 
run ir-keytable -p PROTOCOL -t, then press some buttons on your remote.
If you discovered the correct protocol you should see EV_MSC events together 
with the scancode of the button. eg: 

ir-keytable -p rc-5 -t

Protocols changed to rc-5

 .... HIER KAM DANN MAL NIX :D

Wenn hier nix kommt.. dann mal mit nec probieren, war für die Samsung-Fernbedienung notwendig.
