This is my thought , along with High Memory usage the other issue under gong with CORE3 on my end remote response. as I abbreviated earlier never have that issue on EA#3.
I can definitely rule out (" IR emitter off of its spot ")
Remote response/selection issue is across all.
My observation when we are trying to change Volume , moving Page's up/down , Fast forwarded/ rewind the remote is not responding as quick as it used to be on EA Controller.
IR controlled devises
IP controlled devises
SDPC/MAC ID controlled devises.
The issue has to be with in the CORE controller.
