rpi-imager (installable through apt) has an option to install media player OS's directly as well, including the latest LibreELEC. But I must admit, Taliesyn , I am surprised and disappointed that they don't have an installer for Linux.
Scroll to the very end of the list of installable os options, there you can install any iso that you have downloaded.
Raspberry Pi imager works just fine.
I think you need to tell the tv to ignore the pi. I had the same issue and dug around on the tv's setting to stop that. I dont recall off hand where it was in the tv's setting exactly.
You may want to look into the Raspberry Pi imaging tool as well. It is located on that page, just the next section down.
Wait dont you mean decreasing?
Wild guess... you hit the wifi switch by accident and turned it off. look for the switch and flip it to on again..
Did you run it as root? 
Did you type the pathways into kodi, cut and paste, or update the config file directly?
I'm thinking a spelling error in the path. the l's(L) and 1's (one) look a lot alike.
copied the the error output from your first post into a text editor.. the 1's seem to be correct... next this to check is an errant space at the end of the nfs path.
another thought just occurred to me, it needs dns because it needs to phone home... :O
I need to check this out.
I'm thinking it is a dns/dhcp issue. is your nas dynamic or static addressed? and are you using just the gateway as your sole router on your network?
Try su and not sudo
then try sd creator
Sounds like a rights access issue. On the subfolders check to see if the pi has access rights to the folder and files in them.
Sounds like an issue with ACPI. Since ACPI is a specification and not a formalized standard. This means it can implemented any way the manufacturer. ACPI is really hit and miss from manufacturers
Is it 'hip' these days to use annoyingly large fonts in our forum?
Please stop that, otherwise those posts might 'accidentally' get lost.
And what do you mean by "no hypothesis"?
I take it the 'Large fonts' you speak of are the ones in place of an image to help id a user. If that is the case it is a function of the forum/message board software not something that a user does.
ah there it is... i keep looking for the familiar orange icon.... 
many thanks
Is there an option in the new forum software for rss feeds of forum messages?
if not, WAAAAAAAAA! 
If you have another device that outputs 1080 at 60hz I'd try that on the monitor to test it. It may be an issue with the monitor itself.
Once that has been eliminated, you may need to look at any addons installed those may be the cause.
If you can (I'm assuming this is a laptop or desktop) have you tried a fresh install on another boot media/device and see if it works then.
