First up we have disc one of season eight of The Simpsons. Despite the disc appearing to be in good shape (I bought it personally at release) with minor, if any scratches, MakeMKV seems to have issue seeing the second layer of the disc, and thus half of the episodes. I've tried MakeMKV on a Mac and PC with similar results, and I've tried both manual mode and ripping MKVs from the disc backed up to a local drive. The disc will load on a standalone Blu-Ray. player connected to the TV and bring me to the menu, but selecting any of the second half of episodes (presumably on the second layer) causes the player to outright "crash" and kick me back to the player's interface. I'm wondering if maybe I'm just on the losing end of disc rot on this one.
Second we have disc one of a the 2006 "Tenth Anniversary" complete series release for The Powerpuff Girls. Similar to the above situation, the disc is in fairly good shape, but MakeMKV on two platforms has issues and can't seem to read the second half of the episodes on the disc, presumably on the second layer. In addition, while the above "Simpsons" DVD will at least get me to a main menu on a standalone player, this disc seems to not load whatsoever.
Oh and my Blu-Ray drive connected to my PC/Mac makes some nasty grinding noises while trying to access the data on the disc.
