Sub out 3 and 4 still dont work when played DTS X. There are still others but I do not follow all of them. This bug is out there since the unit was released and well known. That they still did not fix it speaks volume to me.What major bugs? Haven’t noticed any major bugs?
Update process was indeed pants last year but after certain update got better - still indeed it’s not as good as it could be but thankfully latest version is stable so don’t need to update it any more.
That’s the price to pay with boutique manufacturers
