I found that LE doesn't like PCs. I could not make it work from a HDD, I thought I finally found a use for the boat anchor with a 40 GB HDD. Works fine from a flash drive.
Maybe I'll try it on one of my 10 GB IDE drives one day. I know I still have them for some reason.
Have you looked at:
LIRC - Linux Infrared Remote Control
It is very "linuxy" technical, but it might help.
I know you don't think ir-keytable has anything to do with lirc, but read the page until you get to it.
Have you tried going to lirc.org? There is a section on how to use ir-keytable, I don't know how different LE is. I always assUmed it used the same kernel as Ubuntu, I am probably wrong.
You could check the time zone in Settings>interface>regional.
It is supposed to get the time and date from you network, it may get it as GMT, so your time zone is important.
How long does your TV take to boot up when you press the power button on the TV, mine takes several seconds. Screensaver is standby, not off.
I do know for sure that lirc is included in the newer linux/Ubuntu kernel. I was slapped down a while ago when I tried to correct somebody about using sytemctl to stop and start lirc in libreelec, I know that is how in linux/Ubuntu, don't know about libreelec.
Comparing LibreELEC with KodiUbuntu is pretty much a waste of time, you have to forget most of what you trial and errored and start anew.
Ir-keytable is used to configure the seemingly invisible lirc.
Lirc.org is a good place to find out how to make lirc work the way you want it to. However it is huge and filled with outdated and new information. I do remember seeing something about conflicts with the kernel when programming that I could not understand because it is way too "linux" for me.
In windows some key strokes, like the green button, are defined by registry values, Makes me wonder about those odd ones in LibreELEC.
If you are using a GPIO IR receiver. You should only need to edit the /flash/config.txt so that dtoverlay=lirc-rpi is not commented out. Then un install lirc if you installed it. Then put your RC-5 lircd.conf in the /storage/.config directory.
Forget about all of that old fashioned stuff.
Details?

What versions of libreelec and kodi
What type of network connection
Did it ever work, if so what is new
For closure sake; I finally found this Hauppauge WinTV-HVR-1250 - LinuxTVWiki
it explains that the IR function is NOT supported by the cx23885 chip driver. It does not explain why the driver loads and finds all of the hardware.
I have a Hauppauge HVR1250 PCIe with a built-in IR receiver with the correct cable. No response from ir-keytable -t.
Tvheadend works for OTA live TV.
dmesg says it sees the card and the IR. I have tried installing lirc. I have done
modprobe cx23885 enable_885_ir=1
no joy.
Installed and setup lirc like I had on my RPi; no help.
I found this solution that sounds like it will work for my particular card; HVR1250 that the computer sees as a HVR1270 with a CX23885 chip. cx23885: Add IR Rx support for HVR-1270 boards - Patchwork
The only problem for me is I have absolutely no idea how to go about using the patch. The author says it's a "simple cut and paste", to what where? It may not even apply to kernel 4.9. Any help appreciated.
The patch is all the way at the end.
Here is dmesg same hardware libreelec 7.90.009. AMD PC , running on install USB DRIVE, Hauppauge HVR-1250. notice kernel lirc is invoked.
Still have not got correct cable for the IR.
Gujal said he was going to try it on Ubuntu server.
Also the plugs on the card don't change with OS.
Also I was under the impression, from gujal's reports, that the kernel support for the Hauppauge card was the same.
I had invested many hours searching for how to get the IR working, believe it or not, this thread is one of the more helpful.
I didn't think it was such a stretch.
I recently installed my Hauppauge HVR-1250 into a Ubuntu 16.04 and decided to try the IR. I ordered a IR receiver and plugged it in, after 2 days of trying to get it to work I finally noticed that I plugged it into the 1/8 inch audio input not the 1/16 inch IR input! 
Now to order from Hauppauge since they seem to be the only ones that sell receivers with the correct plug.
I think that was my problem, however I did notice that installing lirc and doing lirc-setup that all of the correct files ended up in the correct Linux places. It turns out that almost all of the tuts are wrong in one way or another.
My dmesg is very different re the IR
I will try to get back later.
dmesg no lirc installed
What I have done on another Ubuntu 16.04 machine:
sudo dd if=/dev/mmcblk0p2 of=/home/don/Sdcard
sudo losetup /dev/loop0 /home/don/SDcard
sudo mkdir /media/don/rpi_card
Sudo mount /dev/loop0 /media/don/rpi_card
So, now I can read the files!
Is there a way to re create the partition with a new super block; since all of the super blocks were corrupt?
Maybe make a new LibreELEC SD card, then cp everything over?
My RPi fell off the shelf, now the ext4 partition of the SD card is not mountable, automatic repair ran "force fsck" and says it is beyond repair.
There is a file or 2 I would like to try to get off it, is there any hope?
I put it on my Ubuntu 16.04 machine, I cannot read the ext4 partition, but gparted can see it.
I tried gpart; it could not read it.
The link I provided has it hidden, you have to scroll down and look on the right side. That's really all I know about it I just saw it while downloading for my Ubuntu machine.
It is a .deb package for armhf. I doubt they would release source since they charge for commercial use.
Teamviewer now has a RPi version
TeamViewer Linux Download
Now how to install it on LibreELEC?
