What IR files are you using? In the Mega List 22 Beta there is a Humax IRHD-1000S/ME file. This file has the toggle codes that should fix your 0000 or 2222 not working. The file has both A and B codes in it.
In programming, on the remote each button you are putting the codes on are now going to be macros, in the macro your going to insert the A-B Toggle IR Code for the command type, when that's placed on the button insert the Digit 1A and the Digit 1B inside the bracket. Do this for all commands your going to use.
Try that and let us know if things get better for you.
There's no worse feeling than that millisecond you're sure you are going to die after leaning your chair back a little too far.
