delay in CEC responding to remote

Rasp Pi 2 w/ 0.5.1 on samsung F8500 (also 5300 LED - same issue).

 

I use the samsung remote to control rasplex and it works great, except for one issue. When I turn on the TV it will return to rasplex (HDMI 2), just as I left it when I turned off the TV prior (I keep the raspberry on 24/7). However, it will take up to 8 seconds for rasplex/TV to respond to inputs on the samsung remote. I have experimented using different HDMI ports, as well as rasplex settings to never suspend/sleep, even when I turn off the tv. The problem remains. If I cycle through the HDMI sources and return to HDMI 2 (rasplex), then rasplex will respond to the CEC remote inputs instantly.

 

Is there anyway to correct this delay? Or, is this just the nature of how samsung uses CEC for third-party devices?

Yep this is true of my 2012 Samsung TV as well. When turning on the TV It can take up to 10 seconds between the picture appearing and a button press having any impact. Happens with both Rasplex on the pi, Rasplex on a pi2 and also the pulse8 HDMI-CEC adapter so I'm pretty sure it's just how HDMI-CEC is implemented on Samsung TVs. I've not found any Samsung TV settings that can improve the wait, but it's not too bad.
