That log helps some of your keys are working (as, indeed, you've already said), but I've no experience with handling TV remotes via CEC (my remotes are all directly connected to RPi systems, except for Android tablets using things like YATSE).
If you do 'tail -f' the log, youll be able to isolate the key actions which don't get passed to the RPi - with that detail it should be possible to list those which do, but don't provoke an action, and map them in a keyboard.xml and /or a remote.xml.

I'm sorry to hear your comment about stmlabs, as I've found a well formatted question with sufficient detail will get a response (and the response time has to depend on whether someone feel they have enough information to respond)
