FLIRC, Chromebox, Kodi, and my URC-8910

[timewalker]

Ok, thanks to everyone here, I have multiple URC-8910s all customized for my living room and bedroom (TV, Xbox 360, Xbox One, Yamaha receiver, Projector, etc.).
But I want to replace my aging first generation Apple TVs (running XBMC on Crystalbuntu) with modern Chromeboxes (running Kodi on Kodibuntu).

At first I just plugged in my Ortek IR receiver and used the JP1, but as anyone who has done that knows, there are some keys that don't map correctly. The "Info" key only works as a right-click, etc.

So I bought a FLIRC dongle, and programmed it, and I got it to work for every key and function I needed. Huzzzah!

Except, when I hold the arrow keys down, they don't repeat to scroll through selections (e.g. Movies or TV episodes).

I tried the inter-key delay in FLIRC, every setting from 0-6, and none of it made a difference.

Then I tried programming it with different codes than the Ortek (the original RCA DVD code that the Xbox used, a basic Panasonic code since I don't have any other devices from that brand), and while they would repeat for a scroll, either it was unreliable, or it caused issues with other keys not sending every time.

I know, this should probably go to the FLIRC forums, but they are down right now, so I figured I would post here in case anyone else has run into this. And I can always copy/paste there later.

Thanks for any help.
