Coming from a tech background and still being registered on a number of tech forums I can say that Linux users are generally more evangelical than Windows users.
Windows users (including me) are generally a) aware of the hellhole they are operating in and b) spend less time playing with the OS itself and so are less concerned about it.
Reverted to the official v11 release and things are working correctly.
My Pulse-Eight CEC adapter arrived so I installed LibreELEC-Generic-legacy.x86_64-12.0-nightly-20230531 onto an old HP PC using a 128GB SSD, connected up the adapter and the TV's remote just worked. Today, before spending money on new hardware I just wanted to chec a couple of things. Hooked up the PC to the Panasonic TV again.
What I want is, as the RPi3 does, is to turn the TV off and come back later and press any key on the mini keyboard attached to the Pi and for the TV to turn on and go to the appropriate AV with Kodi on it.
Not only is it not doing that but the TV remote no longer works.
I've tried playing with the CEC settings & the screensaver settings but can't get things working.
Can someone tell me what settings I need to change please.
Unless the hardware would require a different install then you shouldn't need to reinstall, just hook everything together and turn on.
If you do go the full install route then flash the usb stick (I use balanEtcher) plug into the box, boot from it and install to the ssd BUT before you do that, if you can get the xbmc box running for a bit take a backup - that will allow you to get your current configuration back.
Thanks for that comprehensive reply. The main reason for asking is the move to a different machine which may end up not running LibreElec (but probably will) and if it doesn't is likely to end up on Windows which TVHeadend doesn't run on.
I have the same issue, sort of solved by using FileZilla to transfer from RPi to PC - it switches : to _
My format string is $t$-c%F%R$-e$n.$x
I should be buying a new machine to run LE/Kodi soon. Up to now I've been running TVHeadend on RPi3. I'm having a look at NextPVR. The configuration certainly seems easier than TVHeadend. I'm just interested in how others percieve the pros and cons of the two systems.
If you boot from a MicroSD card and have a look in Settings|LibreElec is your firmware up to date?
I used balenaEtcher on Windows to write the image to an SSD and my RPi4 booted from it without problems.
Thanks - I'll get one on order
Just to double check - if I buy a Pulse8 USB - CEC Adapter I can hook it onto any PC and it will work? Or are there more gotchas? I have an old HP Compaq 8510W I can use to try things out on before committing to a better spec SFF PC.
I'm reading the Amazon reviews and I found this
Needs separate power USB connection to work
in a 1 star review and it baffles me. I know I need to plug it into a USB port but "separate power"?
<< If it took two remote controls to switch off a light v walking across the room to press a switch the WAF was low>>
Thank you for that it made me smile.
Thanks - this is reminding me of IBM 4341 mainframe assembler - that made my head hurt as well.
Thanks for that link, it rather demonstrates the lack of any useful technical information 
I'm guessing you're more hardware oriented than I am (lots of years writing applications, especially database/business) and you've pointed out a weakness in the RPi ie <<On the RPI4 you have four USB ports sharing one PCIe lane >> does this also apply to the Rock machines?
I realise this is in reference to my wife but what does WAF stand for?
One brilliant way is, as I have done when wanting to test an application I've written, get a hex editor and simply alter what's stored on the disk. Great fun if you want to deliberately damage a table.
Badly written software can do it and in part it depends on how the database engine responds to say 25 characters being written to a field that is only big enough for 10, or it can write a character to a field that the engine can't handle. If running over a network a junk character can be introduced by a glitch on the network. Software writing directly to disk when it should go through the engine and overwriting some valid data. Poor transaction handling so that two lots of data are being written simultaneously and some gets in the wrong place on disk. Memory corruption which is subsequently written to disk.
Over the years I've had pretty much all of them.
What might be going on here I don't know. SQLite isn't one I'm overly familiar with (I can use SQL on it but that's because I now SQL) and I'm not familiar with the LE code base (translation I've never even looked at it).
Can one of the developers enlighten me on how the copying from MyVideos120.db to MyVideos121.db is done. If as I'm guessing its read a record, write a record then the table metadata is probably getting screwed, if its a straight copy I'm baffled.
First, thank you for trying to help. However, as you can guess I'm not going to opt for a sat>IP tuner and I really don't care about 4KUHD (at 72 I've seen enough overhyping, but to be fair moving from SD to HD in the US was a big deal, not so much in the UK, and please do not get me started on about PC screens that need to be at 200% to have readable text).
I'll have a look at the Rock machines and see if I can find any performance comparison.
Thanks for that - it explains the very limited command set table 
At least I now have some idea where I'm going and the fact that I'll need to add £40 to my budget for the Pulse8 USB adapter
Out of interest is there any usable documentation regarding CEC out there - if there is I was searching for the wrong terms.
Different setup - I want to reduce it to a single box so that its easier for my wife when things go wrong - back to the old IT standby switch it off, switch it on
<<. The difference with 4kUHD is very noticeable>>
I politely disagree with you.
Still looking for a way to say a box supports CEC if you know one.
<<Those DVB USB dongles are just a heart breaker.>>
With my twin RPi3 setup it works well, it works fine on the RPi4 as long as I only record one programme
<<On the RPI4 you have four USB ports sharing one PCIe lane >>
This is almost certainly the problem. For testing I had Hauppage dual tuner, 3TB powered HDD, wifi keyboard dongle, ethernet
<<and have no issues watching and recording up to 4kUHD>>
My antique eyes would, or at least can't see the difference so why bother <G>
I'm going by this information for the NUCs
and looking only at the onboard CEC section.
How good is the Pulse8 adapter I've found mixed views about it whilst driving myself insane about CEC.
