It's main purpose is ripping not testing, more like 'testing' your car by turning the ignition key. If you want to call it a great ripper fine. Not much of a tester though.
I am not going to waste my time with a program struggling to encode a damaged disc and using a ton of space with it's raw format and expiring on me whenever it feels like it.
My experience was nothing as you describe and I don't understand your claim that it's a waste of time. Not trying to get in an argument over this but this is why i think it's the most logical method/path to use :
First off, with the warner hd-dvd discs going bad (i had an approximate fail rate of 10%, which seemed about average compared to other reports), I don't see why someone wouldn't want to start backing up their discs asap (i did this about 2 years ago when I found this thread), whether it be as playable MKVs or pure ISO backups. Who knows what the fail rate will be five years from now?
And I never once had the program crash on me, if a disc failed in the backup it would just give a "bad disc" message, and with the Warner titles you could even approximate where the layer change was due to how far along the process was upon failing. These failed discs then failed regular playback on my XA2 and Xbox drive, while the successful backups became a completely playable HD-DVD library directly streamable in my HTPC.
The car ignition test isn't a fair comparison - it doesn't really matter to me what the specific encode error was, if MakeMKV failed it was an unplayable disc 100% of the time and there is absolutely no fix for the failed discs. They're dead. With a car there's always a good chance of repair so of course you would want a diagnostic test there. No diagnostic test was going to bring back the 10% of my Warner HD-DVD catalog.
So after using this method I had my entire HD-DVD library with direct-play access in Plex, while I had almost instantly identified with discs I needed to replace with a blu-ray.
I guess i don't understand why you are so dismissive of this method, and I'm hardly the only one to go through and backup their HD-DVD library this way while at the same time identifying the discs that were goners. Many a thread on many a forum were full of postmortems a couple of years ago with people sifting through their HD-DVDs with this exact method.
Not saying however you choose to test is "wrong" I just don't think this method is anything close to a "waste of time"
