List of Failed Discs

[TheGreenOne]

Is there already a list of discs that just won't rip? I'm loving the program but for every issue it blames the drive or the disc. I'm using a 2 year old drive that had maybe 5 hours of use before the last week and a 10 year old drive that had probably never been used. Then most of my discs are brand new, never even played. Still getting a LOT of failed rips. So here is my list (which I will update as I go) of movies that just will not rip. If you've had success with them, please reply so I can know to obtain other copies. Or drop any you're having issues with.

This is NOT knocking makemkv. It's a great program and I'm thankful it exists. This is an attempt at finding a solution.

A Nightmare on Elm Street - blu ray - Rips but the last disk (both movies) has a glitch every ~15 seconds
Twister - 4k
Nope - 4k (blu-ray ripped)
Heat - blu ray
Revenge of the Nerds 2 - DVD
Friday After Next - DVD - can't find the disc

The only one of those I have is Heat (1995). I was able to rip the blu-ray just fine.

Assuming you mean disc 4 of the 14mm case 1080P ANOES collection (I picked it up when Amazon had it for $12 or $13, a couple weeks ago), my rip of Freddy's Dead and New Nightmare play fine. But, since you mentioned it, I ran all of them through MKVToolnix, as straight 1:1 remuxes, and it ID'd one problem spot in The Dream Child (from disc 3), confirmed to cause a playback glitch in both VLC and MPV, both in the pre-remux (MakeMKV's remux) and post-remux files. No reported errors when initially making a backup. I did the same for about 30 other discs, right quick, that I still haven't organized, yet (*_t##.mkv files), and nothing. But, I may make this a thing to do, now, as a sanity check.

'{longpath}.mkv': A block was found at timestamp 00:31:47.297000000 for track number 115. However, no headers were found for that track number. The block will be skipped.
{longpath}.mkv: Error in the Matroska file structure at position 6376587021. Resyncing to the next level 1 element.
The last timestamp processed before the error was encountered was 00:31:46.154000000.
Resyncing successful at position 6379251073.
The first cluster timestamp after the resync is 00:31:47.238000000.

I just re-ripped t01 only, straight from the disc, with a BDR-XS07 (stock 2020 FW), and then a BDR-XD05 (stock 2014 FW), and they were both fine (played that section, then did a MKVToolnix remux). I went to the backup files, did a fresh MakeMKV remux of it from that, and aside from all the drive speed warnings (like I don't know a 5400 RPM HDD reading and writing at the same time is going to be slow), that was also fine.

So, uh...

As for DVDs, I had a few old TV series discs not get recognized in MakeMKV, but the OS saw them OK, and they ripped fine with other software (K3b?). If the OS gives you a correct size and/or volume label and/or disc type, try other software, for DVDs. If on Windows, good old DVD Decryptor and DVDShrink still work as well as ever.
