I've also struggled to write DVDs under W10.

I currently favor UltraIso. I found it simple to use, but it won't work if your writer cannot write to an old DVD disc.

To be fair, it was an external USB DVD writer as the laptop doesn't have a drive, so that could have been part of the problem as well as the cheap disc I used. I think I used ImgBurn (which used to work very well on W7. Also to note is that the installer may contain unwanted extras according to a post I saw).

My writer is in a year old machine and has just about never been used.

I read somewhere that if you're DVD drive has power, it's writing/reading LEDs will be degrading with time. They'll eventually wear out and you'll not be able to read or write DVD's reliably. I've had a few old DVD drives that seemed to fail this way.

My limited experience: I can still read CD-Rs I made in 1998, and have just tested one of the 100 DVD-Rs bought in 2011 (10p each on a spindle): burned fine at x16 using Imgburn, verified OK, now stored for posterity.

In my experience it's not the age of the discs so much as it is the age of the DVD writer. We back up our source control and all of our product builds, so we write 500-800 discs a year. Most writers are only good for 200-300 discs before you start getting increasing write failure rates like you describe. My practice now is to replace the writer if it fails more than 1 disc in 10.

Interesting! But I write probably between 10 and 20 per year. So my writers should last many years. In any case, my desktop is barely a year old, so the writer should be OK.

I'd be looking at that first.
Back when burning speeds quickly went from 1x to 2x, 4x, 8x etc I started running into problems if I tried to burn anything at more than 4x. I've always stuck with 4x out of sheer habit and very rarely run into read or write issues.
Of course I don't burn nearly as many discs today as I used to. But I still wouldn't even bother trying at anything higher than 4x. YMMV, of course, and as you've seen, it does.

You sure about that? Given writable DVD's have only been around for around 20 years, it would be impossible to state how good they are as a long term archival medium. They take guesses on durability of media by calculating how long media take to break down inside a worst case scenario type environment and then extrapolating that figure out for a normal storage environment. But unless you're keeping your DVD's in an environment that maintains the correct temperature and humidity you may find that the data isn't as safe as you thought.
Furthermore, do you test your original DVD backups from time to time and / or transfer them onto newer media? It's not uncommon for someone to think they are fine with their backups, to then go and restore them to find them in a less than perfect condition.
But don't just take my word on it -> https://www.naa.gov.au/information-management/store-and-preserve-information/preserving-information/preserving-cds-and-dvds
It states pretty bluntly that "CDs and DVDs are not suitable for long term archival use".

Quote: CDs and DVDs are not suitable for long term archival use
This statement is incorrect when you are talking about M-discs. Recently I started using only M-discs.

Yes, the 1000 year disc, or so the manufacturer says.
I would be skeptical on that sort of longevity outside of archival conditions. (I'm skeptical on that number even in archival conditions, especially as they invoked "trade secrets")
Keep in mind that proper archives store things inside carefully temperature and humidity control rooms as well as been very rarely disturbed, things that people who throw disks into desk draws / filing cabinets are usually lacking. No doubt, the manufacturer will be quoting 1000 years based on perfect archival conditions.
Personally I would be trusting an actual archive to tell me about long term storage than manufacturers claims when trying to sell consumer grade technology.

Until the "archive" produces actual test results that show that the M disc has a lifetime, say less than a human lifetime, I will trust that my M-discs will outlive me. And I ask no more than that!

I also heard of that attempted molluskstation in the lavatory - very shellfish behavior in my opinion.

Arrgh!
When I saw it was you posting I was expecting a pearl of wisdom.

Doing some environment reporting (temp, humidity, etc.) using Blazor Server on a Pi. Created a new Blazor project in VS 2019 (W10) and named it Environment. Hit F5:
error CS0426: The type name 'Shared' does not exist in the type 'Environment
Does the same building it on the Pi.
Changed name from Environment to environment. Life is good.
Now, to deep fry my turkey. 
Edit: Got a reply to my entry in the asp.net forum. Guy is an all star. "we can't see your code".
I can do better than that on SO.
If you can keep your head while those about you are losing theirs, perhaps you don't understand the situation.

Environment is a existing class, part of the System namespace - so if you start calling your class Environment it may hide load of things ...

Not only that, it won't build.
Thanks.
