Do you have the transponder/frequency in the scan file for Kaffeine? You have to have the frequency, polarity and symbol rate in the file. The file location I gave you earlier is what works for my setup. I do however remember having issues of there being more than one file and location.
For the main two you want:
11760, H, 30000
11880, H, 30000
I happen to be on the computer that I use with Kaffeine, so if I can get it done, I will upload my scan file. It isn't complete, only has been modded for a few of the sats. Takes a bit of time and effort at a couple or more sites to get the right data. Assuming it took, you will need to change the extension to dvb from txt, the forum software didn't like the dvb.
I compared my scanfile.dvb to your scanfile.txt. Everything I checked is the same as what you have listed. But, I still can't scan in the NBC muxes at 103W or the PBS stations on 121W using kaffeine. Even scan and scan-s2 can't lock onto the transponders. w_scan -fs -s S121W0 couldn't lock anything either - I don't know what file w_scan uses so I can't edit it.
