I’ve noticed a difference in behavior from my IR remote when using the N2 vs C2.
When browsing movies in wall mode, the C2 will let you scroll down faster than the image tiles load. While on the N2 the IR remote will only scroll down as fast as the image load.
The N2 experience, as a result, is a far slow feeling.
** I have a 2.4 wireless remote that I primarily use but from time to time if I’m lazy I’ll use my harmony remote & that is where I noticed the behavior change.
