PatrickJB Yes, I've also noticed the LE Settings glitch and at first I thought it is related to new compile flags I used... but it also does that with old settings. Since it's a minor bug and only in LE Settings (which we don't use that often, do we?), I don't care much.
kostaman Thanks for reporting. I think that CEC-related issues your experience are specific to your TV model, at the moment I'm out of ideas on how CEC driver can be improved... you may want to try using libcec-daemon, there's a quick guide by sammaz on previous page of this thread. You have to note that some keys work differently with daemon and need to be remapped.
I'm not fussed with the CEC as i just change source and back and it works. I only use TV remote as a short cut commands without bringing up OSD and stop button.
Turning on Box waiting 5 seconds and then turning on TV seems to work as well.
All buttons work so no libcec-daemon for me.
