My 950 has been flaky with remote inputs for years -- I always thought it was just that the remote was going to crap.
I recently got a new universal remote (Harmony 510) and the 950 is still just as flaky! Infuriating when you need to bump the volume up or down a decent bit.
So I've concluded it's the IR receiver on the 950 that's wonky. I've got a ticket with Outlaw, although I doubt there's much to be done -- I've had my 950 for quite a while, and while there's really no functional need to upgrade, this remote thing is killer.
