No, i didn't see the solution until now, but anyway, the issue seems to be gone now and is working properly after turning everything off for a couple of hours, i didn't do any reboot though.
I have 2 older Onkyo receivers (that i hadn't have issue with) before i got my first Yamaha receiver because it has Auro 3D, and it's given me some of the issues that were mentioned here in this thread, and the firmware update that took forever.... I guess it's the bad impression i got from it that make me want to go back to Onkyo, but you're right, i totally agree with you, given the trend that most of these modern electronics are going with fixing the issues later via firmware update...., i hate it, but there's nothing i can do about it.
I guess that i won't update any firmware right away from now on, and rather wait a while and check here first to see if there's any issue with any future firmware update before i do it.
