complex multiplex encountered

Post by Insidious » Sat May 30, 2020 1:12 pm

Hi guys, first post. I bought the Coach dvd series (yes, I'm old) and am ripping them to my drive. The first couple disks were fine but then I started getting the following error on every disk afterward. Reboot did not help. My drive is an LG WH14NS40 with 1.03 firmware. I don't recall if I flashed it or if that's the way it came, I've had it a while. Did a little searching but didn't find a solution for the CME error. Is it something that can be corrected with a patched drive or are they physical issues with the disks? Thanks for any help.

On some DVDs this is normal. It's the design of MakeMKV to get some data ...
Good Luck :)

I’ve recently run into the same issue. I’m at a loss in determining what the root of the issue is. Turn on debugging and it doesn’t provide anything I can decipher.
The VOBU count is through the roof though and it skips a ton of “less than 120 seconds” pieces.
I’m working with Die Hard 4

I've noticed this happens with TV shows. I think its normal and its MakeMKV having to go through every path in which episodes could be accessed, which can be a lot.

I am also seeing this a lot with series. Previous makemkv versions used to do this from time to time with DVD movies. Now I see it almost every time. Something changed over the last release or recent releases to bring this "feature" about.
