The article I linked to you to is a problem that is hard to fix by updating the flirc.
Basically, MCE/XBOX/Microsoft remotes alternate between 2 different "signals" when you press the same button.
So the solution in the support article aims to capture both signals. You may have to do this a few times for it to work.
If "redo" window comes up then flirc has already recorded that signal. Keep trying to record then it should pick up the other signal, it will say "recorded sucessfully".
This needs to be done for all keys.
The "every second key press doesn't work" issue doesn't usually indicate that Flirc is broken - it's a quirky feature of some older designs of remote.
The issues with the IR receiver on the TV are strange and are outside my knowledge (I just try and troubleshoot common issues), Contact Jason on this link and see if he has an ideas as he is more knowledgeable than I:
I will update this support document (I've been busy with work over the last few months - and have moved house so need to find my stuff again).
In the meantime you can double check they are what they are by programming those keys then opening a text editor and pressing the buttons (as flirc turns up as a keyboard)... or use the "full keyboard" controller to configure flirc to the way you want.
It's been a while since i've been the forum but I thought there was a similar issue that had a solution. Unfortunately I couldn't find that.
If you open a text editor (or anything you can type text in):
- when you press "2" on your remote what key is outputted on the screen?
- when you press "5" on your remote what key is outputted on the screen?
Just to check what key Flirc thinks already exists.
After you upgraded, did you clear the configuration before reprogramming?
If you press the button on your remote control when the flirc programming software is running then the key combination will show up. This is the only method I am aware of.
For deleting the combination it would either require pressing the button that was previously assigned or clearing the configuration completely https://flirc.zendesk.com/hc/en-us/articles/203361609-What-does-Save-Load-Clear-Configuration-mean-
