Well it will not always be hardware... Sometimes with the hardware that is out there software updates will address things. But sometimes its the TV also which is hardware.. Overall I agree that most time it will be on the receiver end but not always.. Just becasue someone replaces something and it works does not mean that will fix everyone's issue.. There are other things that can play a factor like software and software will always play a role in things on how well hardware will perform.. But like I said its not always the case.. Sometimes it's a combination of the two..
