Delayed scroll with IR on N2

Hi, I’m using the latest build although I have had this issue since I moved from my C2 to the N2.

Via IR, scrolling through my movie list is painfully slow, stuttering every few rows. This is not the behavior on my C2 running core. I thought it could be performance specific but the box runs very peppy everywhere else and when I use my USB remote it lighting fast on the scroll down.

Its something specific to IR

Any ideas?
